Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:200 9 certif ication for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in Calif ornia
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hop ping
devices, Serial EEPROMs, microper ipher als, nonvol ati le memory and

2.0 GUIDELINES FOR GETTING
STARTED WITH 16-BIT
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
family of 16-bit Microcontrollers (MCUs) requires
attention to a minimal set of device pin connections
before proceeding with development. The following is a
list of pin names, which must always be connected:
All VDD and VSS pins
(see Section 2.2 “Decoupling Capacitors”)
All AVDD and AVSS pins (regardless if ADC modul e
is not used)
(see Section 2.2 “Decoupling Capacitors”)
•V
CAP
(see Section 2.3 “CPU Logic Filter Capa ci tor
Connection (VCAP)”)
•MCLR pin
(see Section 2.4 “Master Clear (MCLR) Pin”)
PGECx/PGEDx pins used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes
(see Section 2.5 “ICSP Pins”)
OSC1 and OSC2 pins when external oscillator
source is used
(see Section 2.6 “External Oscillato r Pin s”)
Additionally, the following pins may be required:
•V
REF+/VREF- pins used when external voltage
reference for ADC module is implemented
2.2 Decoupling Capacitors
The use of decoupling capacitors on every pair of
power supply pins, such as VDD, VSS, AVDD and
AVSS is required.
Consider the following criteria when using decoupling
capacitors:
Value and type of capacitor: Recommendation
of 0.1 µF (100 nF), 10-20V. This capacitor should
be a low-ESR and have resonance frequency in
the range of 20 MHz and higher. It is
recommended that ceramic capacitors be used.
Placement on the printed circuit board: The
decoupling capacitors should be placed as close
to the pins as possible. It is recommended to
place the capacitors on the same side of the
board as the device. If space is constricted, the
capacitor can be placed on another layer on the
PCB using a via; however, ensure that the trace
length from the pin to the capacitor is within
one-quarter inch (6 mm) in length.
Handling high freque nc y nois e : If the board is
experiencing high frequency noise, upward of
tens of MHz, add a second ceramic-type capacitor
in parallel to the above described decoupling
capacitor. The value of the second capacitor can
be in the range of 0.01 µF to 0.001 µF. Place this
second capacitor next to the primary decoupling
capacitor. In high-spe ed circuit designs, consider
implementing a decade pair of capacitances as
close to the power and ground pins as possible.
For example, 0.1 µF in parallel with 0.001 µF.
Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first,
and then to the device pins. This ensures that the
decoupling capacitors are first in the power chain.
Equally important is to keep the trace length
between the capacitor and the power pins to a
minimum thereby reducing PCB track inductance.
Note 1: This data sheet summarizes the features
of the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F/PIC24H
Family Reference Manual. Please see
the Microchip web site
(www.microchip.com) for the latest
dsPIC33F/PIC24H Family Reference
Manual sections.
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Note: The AVDD and AVSS pins must be
connected independent of the ADC
voltage reference source.

FIGURE 2-1: RECOMMENDED
MINIMUM CONNECT I ON
2.2.1 TANK CAPACITORS
On boards with power traces running longer than six
inches in length, it is suggested to use a tank capacitor
for integrated circuits including MCUs to supply a local
power source. The value of the tank capacitor should
be determined based on the trace resistance that
connects the power supply source to the device, and
the maximum current drawn by the device in the
application. In other words, select the tank capacitor so
that it meets the acceptable vol tage sag at the device.
Ty pical values range from 4.7 µF to 47 µF.
2.3 CPU Logic Filter Capacitor
Connection (VCAP)
A low-ESR (< 5 Ohms) capacitor is required on the
VCAP pin, which is used to stabilize the voltage
regulator output voltage. The VCAP pin must not be
connected to VDD, and must have a capacitor between
4.7 µF and 10 µF, 16V connected to ground. The type
can be ceramic or tantalum. Refer to Section 28.0
“Electrical Characteristics” for additional
information.
The placement of this capacitor should be clos e to the
VCAP. It is recommended that the trace length not
exceed one-quarter inch (6 mm). Refer to Section 25.2
“On-Chip Voltage Regulator” for details.
2.4 Master Clear (MCLR) Pin
The MCLR pin provides for two specific device
functions:
Devic e Re se t
Device programming and debugging
During device programming and debugging, the
resistance and capacitance that can be added to the
pin must be considered. Device programmers and
debuggers drive the MCLR pin. Consequently,
specific voltage levels (VIH and VIL) and fast signal
transitions must not be adversely affected. Therefore,
specific values of R and C will need to be adjusted
based on the application a nd PCB requirements.
For example, as shown in Figure 2-2, it is
recommended that the capacitor C, be isolated from
the MCLR pin during programming and debugging
operations.
Place the components shown in Figure 2-2 within
one-quarter inch (6 mm) from the MCLR pin.

2.5 ICSP Pins
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming™ (ICSP™) and debugging
purposes. It is recommended to keep the trace length
between the ICSP connector and the ICSP pins on the
device as short as possible. If the ICSP connector is
expected to experience an ESD event, a series resistor
is recommended, with the value in the range of a few
tens of Ohms, not to exceed 100 Ohms.
Pull-up resisto rs, series diodes, and capacitors on th e
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger
communications to the device. If such discrete
components are an application requirement, they
should be removed from the circuit during
programming and debugging. Alternatively, refer to the
AC/DC characteristics and timing requirements
information in the respective device Flash
programming specification for information on
capacitive loading limits and pin input voltage high (VIH)
and input low (VIL) requirements.
Ensure that the “Communication Channel Select”
(i.e., PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® ICD 2, MPLAB® ICD 3 or MPLAB® REAL
ICE™.
For more information on ICD 2, ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip website.

Guide” DS51331

2.6 External Oscillator Pins
Many MCUs have options for at least two oscillators: a
high-frequency primary oscillator and a low-frequency
secondary oscillator (refer to Section 9.0 “Oscillator
Configuration” for details).
The oscillator circuit should be placed on the same
side of the board as the device. Also, place the
oscillator circuit close to the respective oscillato r pins,
not exceeding one-half inch (12 mm) distance
between them. The load capacitors should be placed
next to the oscillator itself, on the same side of the
board. Use a grounded copper pour around the
oscillator circuit to isolate them from surrounding
circuits. The grounded copper pour should be routed
directly to the MCU ground. Do not run any signal
traces or power traces inside the ground pour. Also, if

2.7 Oscillator Value Conditions on
Device Start-up
If the PLL of the target device is enabled and
configured for the device start-up oscillator, the
maximum oscillator source frequency must be limited
to 8 MHz for st art-up with the PLL enabled to comply
with device PLL start-up conditions. This means that if
the external oscillator frequency is outside this range,
the application must start-up in the FRC mode first. The
default PLL settings after a POR with an oscillator
frequency outside this range will violate the device
operating speed.
Once the device powers up, the application firmware
can initialize the PLL SFRs, CLKDIV and PLLDBF to a
suitable value, and then perform a clock switch to the
Oscillator + PLL clock source. Note that clock switching
must be enabled in the device Configuration word.
2.8 Configuration of Analog and
Digital Pins During ICSP
Operations
If MPLAB ICD 2, ICD 3 or REAL ICE is sel ected as a
debugger, it automatically initializes all of the A/D input
pins (ANx) as “digital” pins, by setting all bits in the
AD1PCFGL regist er.
The bits in this register that correspond to the A/D pins
that are initialized by MPLAB ICD 2, ICD 3 or REAL
ICE, must not be cleared by the user application
firmware; otherwise, communication errors will result
between the debugger and the device.
If your application needs to use certain A/D pins as
analog input pins during the debug session, the user
application must clear the corresponding bits in the
AD1PCFGL register during initialization of the ADC
module.
When MPLAB ICD 2, ICD 3 or REAL ICE is used a s a
programmer, the user application firmware must
correctly configure the AD1PCFGL register. Automatic
initialization of this register is only done during
debugger operation. Failure to correctly configure the
register(s) will result in all A/D pins being recognized as
analog input pins, resulting in the port value being read
as a logic ‘0’, which may affect user application
functionality.
2.9 Unused I/Os
Unused I/O pins should be configured as outputs and
driven to a logic-low state.
Alternatively, connect a 1k to 10k resistor between VSS
and the unused pins.

PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
3.0 CPU
3.1 Overview
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 CPU module has a 16-bit
(data) modified Harvard architecture with an enhanced
instruction set and addressi ng modes. The CPU has a
24-bit instruction word with a variable length opcode
field. The Program Counter (PC) is 23 bits wide and
addresses up to 4M x 24 bits of user program memory
space. The actual amount of program memory
implemented varies by device. A single-cycle
instruction prefetch mechanism is used to help
maintain throughput and provides predictable
execution. All instructions execute in a single cycle,
with the exception of instructions that change the
program flow, the double word move (MOV.D)
instruction and the table instructions. Overhead-free,
single-cycle program loop constructs are supported
using the REPEAT instruction, which is interruptible at
any point.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices have sixteen,
16-bit working registers in the programmer’s model.
Each of the working registers can serve as a data,
address or address offset register. The 16th working
register (W15) operates as a software Stack Pointer
(SP) for interrupts and calls.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 instruction set includes
many addressing modes and is designe d for optimum
C compiler efficiency. For most instructions, the
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 is capable of executing a data
(or program data) memory read, a working register
(data) read, a data memory write and a program
(instruction) memory read per instruction cycle. As a
result, three parameter instructions can be supported,
allowing A + B = C operations to be executed in a single
cycle.
A block diagram of the CPU is shown in Figure 3-1, and
the programmer’s model for the PIC24HJ32GP302/
304, PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/
X04 is shown in Figure 3-2.
3.2 Data Addressing Overview
The data sp ace can be linearly addressed as 32K words
or 64 Kbytes using an Address Generation Unit (AGU).
The upper 32 Kbytes of the data sp ace memory map can
optionally be mapped into program space at any 16K
program word boundary defined by the 8-bit Program
S pace Visibility Page (PSVP AG) register . The program to
data space mapping feature lets any instruction access
program space as if it were data space.
The data space also includes 2 Kbytes of DMA RAM,
which is primarily used for DMA data transfers, but may
be used as general purpose RAM.
Note 1: This data sheet summarizes the features

3.3 Special MCU Features
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 features a 17-bit by 17-
bit, single-cycle multiplier. The multiplier can perform
signed, unsigned and mi xed-sign multiplication. Using
a 17-bit by 17-bit multiplier for 16-bit by 16-bit
multiplication makes mixed-sign multiplication
possible.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices support 16/16
and 32/16 integer divide operations. All divide
instructions are iterative operations. They must be
executed within a REPEAT loop, resulting in a total
execution time of 19 instruction cycles. The divide
operation can be interrupted during any of those
19 cycles without loss of data.
A multi-bit data shifter is used to perform up to a 16-bit,
left or right shift in a single cycle.

3.5 Arithmetic Logic Unit (ALU)
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 AL U is 16 bits wide and
is capable of addition, subtraction, bit shifts and logic
operations. Unless otherwise mentioned, arithmetic
operations are two’s complement in nature. Depending
on the operation, the ALU can affect the values of th e
Carry (C), Zero (Z), Negative (N), Overflow (OV) and
Digit Carry (DC) Status bits in the SR register. The C
and DC S tatus bit s operate as Borrow and Digit Borrow
bits, respectively, for subtraction operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
For information on the SR bits af fected by each instruc-
tion, refer to the “16-bit MCU and DSC Programmer s
Reference Manual” (DS70157).
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 CPU incorporates
hardware support for both multiplication and division.
This includes a dedicated hardware multiplier and
support hardware for 16-bit-divisor divisio n.
3.5.1 MULTIPLIER
Using the high-speed 17-bit x 17-bit multiplier , the ALU
supports unsigned, signed or mixed-sign operation in
several MCU multiplication modes:
16-bit x 16-bit signed
16-bit x 16-bit unsigned
16-bit signed x 5-bit (literal) unsigned
16-bit unsigned x 16-bit unsigned
16-bit unsigned x 5-bit (literal) unsigned
16-bit unsigned x 16-bit signed
8-bit unsigned x 8-bit unsigned
3.5.2 DIVIDER
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:
32-bit signed/16-bit signed divide
32-bit unsigned/16-bit unsigned divide
16-bit signed/16-bit signed divide
16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0
and the remainder in W1. 16-bit signed and unsigned
DIV instructions can specify any W register for both
the 16-bit divisor (Wn) and any W register (aligned)
pair (W(m + 1):Wm) for the 32-bit dividend. The divide
algorithm takes one cycle per bit of divisor, so both
32-bit/16-bit and 16-bit/16-bit instructions take the
same number of cycles to execute.
3.5.3 MULTI-BIT DATA SHIFTER
The multi-bit data shifter is capable of performing up to
16-bit arithmetic or logic righ t shifts, or up to 16-bit left
shifts in a single cycle. The source can be either a
working register or a memory locati on.
The shifter requires a signed binary value to determine
both the magnitude (number of bits) and direction of the
shift operation. A positive value shifts the operand right.
A negative value shifts the operand left. A value o f ‘0
does not modify the operand.

4.0 MEMORY ORGANIZATION
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 architecture features
separate program and data memory spaces and
buses. This architecture also allows the direct access
of program memory from the data space during code
execution.
4.1 Program Address Space
The program address memory space of the
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices is 4M instructions.
The space is addressable by a 24-bit value derived
either from the 23-bit Program Counter (PC) during
program execution, or from table operation or data
space remapping as described in Section 4.4
“Interfacing Program and Data Memory Spaces”.
User application access to the program memory space
is restricted to the lower half of the address range
(0x000000 to 0x7FFFFF). T he exception is the use of
TBLRD/TBLWT operations, which use TBLPAG<7> to
permit access to the Configuration bits and Device ID
sections of the configuration memory space.
The memory map for the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices is shown in Figure 4-1.

4.1.1 PROGRAM MEMORY
ORGANIZATION
The program memory space is organized in
word-addressable blocks. Although it is treated as
24 bits wide, it is more appropriate to think of each
address of the program memory as a lower and upp er
word, with the upper byte of the upper word being
unimplemented. The lower word always has an even
address, while the upper word has an odd address, as
shown in Figure 4-2.
Program memory addresses are always word-aligned
on the lower word, an d addresses are incremented or
decremented by two during code execution. This
arrangement provides compatibility with data memory
space addressing and makes data in the program
memory space accessible.
4.1.2 INTERRUPT AND TR AP VECTORS
All PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices reserve the
addresses between 0x00000 and 0x000200 for
hard-coded program execution vectors. A hardware
Reset vector is provided to redirect code execution
from the default value of the PC on device Reset to the
actual start of code. A GOTO instruction is programmed
by the user application at 0x000000, with the actual
address for the start of code at 0x000002.
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices also have two
interrupt vector tables, located from 0x000004 to
0x0000FF and 0x000100 to 0x0001FF. These vector
tables allow each of the device interrupt sou rces to be
handled by separate Interrupt Service Routines (ISRs).
A more detailed discussion of the interrupt vector
tables is provided in Section 7.1 “Interrupt Vector
Table.

PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
4.2 Data Addre ss Space
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 CPU has a separate
16-bit wide data memory space. The data space is
accessed using separate Address Generation Units
(AGUs) for read and write operations. The data
memory maps are shown in Figure 4-3 and Figure 4-4.
All Effective Addresses (EAs) in the data memory space
are 16 bit s wide and point to bytes within the d ata space.
This arrangement gives a data space address range of
64 Kbytes or 32K words. The lower half of the data
memory space (that is, when EA<15> = 0) is used for
implemented memory addresses, while the upper half
(EA<15> = 1) is reserved for the Program Space
Visibility area (see Section 4.4.3 “Reading Data from
Program Memory Using Program Space Visibility”).
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices implement up to
8 Kbytes of data memory. Should an EA point to a
location outside of this area, an all-zero word or byte is
returned.
4.2.1 DATA SPACE WIDTH
The data memory space is organized in byte
addressable, 16-bit wide blocks. Data is aligned in data
memory and registers as 16-bit words, but all data
space EAs resolve to bytes. The Least Significant
Bytes (LSBs) of each word have even addresses, while
the Most Significant Bytes (MSBs) have odd
addresses.
4.2.2 DATA MEMORY ORGANIZATION
AND ALIGNMENT
To maintain backward compatibility with PIC® MCU
devices and improve data space memory usage
efficiency, the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
instruction set supports both word and byte operations.
As a consequence of byte accessibility, all effective
address calculations are internally scaled to step
through word-aligned memory. For example, the core
recognizes that Post-Modified Register Indirect
Addressing mode [Ws++] results in a value of Ws + 1
for byte operations and Ws + 2 for word operations.
A data byte read, reads the complete word that
contains the byte, using the LSB of any EA to
determine which byte to select. The selected byte is
placed onto the LSB of the data path. That is, data
memory and registers are organized as two parallel
byte-wide entities with shared (word) address decode
but separate write lines. Data byte writes only write to
the corresponding side of the array or register that
matches the byte a dd re ss.
All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations, or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap is generated. If the error occurred on a read, the
instruction underway is completed. If the error occurred
on a write, the instruction is executed but the write does
not occur. In either case, a trap is then executed,
allowing the system and/or user application to examine
the machine state prior to execution of the address
Fault.
All byte loads into any W register are loaded into the
Least Significant Byte. The Most Significant Byte is not
modified.
A sign-extend instruction (SE) is provided to allow user
applications to translate 8-bit signed data to 16-bit
signed values. Alternatively, for 16-bit unsigned data,
user applications can clear the MSB of any W register
by executing a zero-extend (ZE) instruction on the
appropriate address.
4.2.3 SFR SPACE
The first 2 Kbytes of the Near Data S pace, from 0x0000
to 0x07FF, is primarily occupied by Special Function
Registers (SFRs). These are used by the
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 core and peripheral modules
for controlling the operation of the device.
SFRs are distributed among the modules that they
control, and are generally grouped together by module.
Much of the SFR space contains unused addresses;
these are read as ‘0’.
4.2.4 NEAR DATA SPACE
The 8 Kbyte area between 0x0000 and 0x1FFF is
referred to as the near data space. Locations in this
space are directly addressable via a 13-bit absolute
address field within all memory direct instructions.
Additionally , the whole data space is addressable using
MOV instructions, which support Memory Direct
Addressing mode with a 16-bit address field, or by
using Indirect Addressing mode using a working
register as an address pointer.
Note: The actual set of peripheral features and
interrupts varies by the device. Refer to
the corresponding device tables and
pinout diagrams for device-specific
information.

4.2.5 DMA RAM
The PIC24HJ32GP302/304 devices contain 1 Kbytes
of dual ported DMA RAM located at the end of X data
space. The PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices contain 2 Kbytes of
dual ported DMA RAM located at the end of X data
space, and is a part of X data space. Memory
locations in the DMA RAM space are accessible
simultaneously by the CPU and the DMA controller
module. DMA RAM is utilized by the DMA controller to
store data to be transferred to various peripherals
using DMA, as well as data transferred from various
peripherals using DMA. The DMA RAM can be
accessed by the DMA controller without having to
steal cycles from the CPU.
When the CPU and the DMA controller attempt to
concurrently write to the same DMA RAM location, the
hardware ensures that the CPU is given precedence in
accessing the DMA RAM location. Therefore, the DMA
RAM provides a reliable means of transferring DMA
data without ever having to stall the CPU.

Note: DMA RAM can be used for general
purpose data storage if the DMA function
is not required in an application.

4.2.6 SOFTWARE STACK
In addition to its use as a working register, the W15
register in the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices is also used as a software Stack Pointer. The
Stack Pointer always points to the first available free
word and grows from lower to higher addresses. It
pre-decrements for stack pops and post-increments for
stack pushes, as shown in Figure 4-5. For a PC push
during any CALL instruction, the MSb of the PC is
zero-extended before the push , ensuri ng tha t the MSb
is always clear.
The Stack Pointer Limit register (SPLIM) associated
with the S t ack Pointer sets an upper address boundary
for the stack. SPLIM is uninitialized at Reset. As is the
case for the Stack Pointer, SPLIM<0> is forced to ‘0
because all stack operations must be word aligned.
Whenever an EA is generated using W15 as a source
or destination pointer, the resulting address is
compared with the value in SPLIM. If the contents of
the Stack Pointer (W15) and the SPLIM register are
equal and a push operation is performed, a stack error
trap does not occur. The stack error trap occurs on a
subsequent push operation. For example, to cause a
stack error trap when the stack grows beyond address
0x2000 in RAM, initialize the SPLIM with the value
0x1FFE.
Similarly, a St ack Pointer underflow (stack error) trap is
generated when the Stack Pointer address is found to
be less than 0x0800. This prevents the stack from
interfering with the Special Function Register (SFR)
space.
A write to the SPLIM register should not be immediately
followed by an indirect read operation using W15.
FIGURE 4-5: CALL STACK FRAME
4.2.7 DATA RAM PROTECTION FEATURE
The PIC24H product family supports Data RAM
protection features that enable segments of RAM to be
protected when used in conjunction with Boot and
Secure Code Segment Security . BSRAM (Sec ure RAM
segment for BS) is accessible only from the Boot
Segment Flash code when enabled. SSRAM (Secure
RAM segment for RAM) is accessible only from the
Secure Segment Flash code when enabled. See
Table 4-1 for an overview of the BSRAM and SSRAM
SFRs.
4.3 Instruction Addressing Modes
The addressing modes shown in Table 4-35 form the
basis of the addressing modes optimized to support the
specific features of individual instructions. The
addressing modes provided in the MAC class of
instructions differ from those in the other instruction
types.
4.3.1 FILE REGISTER INSTRUCTIONS
Most file register instructions use a 13-bit address field
(f) to directly address data present in the first 8192
bytes of data memory (near data space). Most file
register instructions employ a working register, W0,
which is denoted as WREG in these instructions. The
destination is typically either the same file register or
WREG (with the exception of the MUL instruction),
which writes the result to a register or register pair . The
MOV instruction allows additional flexibility and can
access the entire data space.
4.3.2 MCU INSTRUCTIONS
The three-operand MCU instructions are of the form:
Operand 3 = Operand 1 <function> Operand 2
where:
Operand 1 is always a working register (that is, the
addressing mode can only be reg ister direct), which is
referred to as Wb.
Operand 2 can be a W register, fetched from data
memory, or a 5-bit literal. The result location can be
either a W register or a data memory locati on. The fol-
lowing addressing modes are supported by MCU
instructions:
Register Direct
Register Indirect
Register Indirect Post-Modified
Register Indirect Pre-Modified
5-bit or 10-bit Literal
Note: A PC push during exception processing
concatenates the SRL register to the MSb
of the PC prior to the push.

different subsets of these addressing
modes.

TABLE 4-35: FUNDAMENTAL ADDRESSING MODES SUPPORTED
4.3.3 MOVE (MOV) INSTRUCTION
Move instructions provide a greater degree of address-
ing flexibility than other instructions. In addition to the
Addressing modes supported by most MCU instruc-
tions, MOV instructions also support Register Indirect
with Register Offset Addressing mode, also referred to
as Register Indexed mode.
In summary, the following addressing modes are
supported by move instructions:
Register Direct
Register Indirect
Register Indirect Post-modified
Register Indirect Pre-modified
Register Indirect with Register Offset (Indexed)
Register Indirect with Litera l Offset
8-bit Literal
16-bit Lite ral
4.3.4 OTHER INSTRUCTIONS
Besides the addressing modes outlined previously , some
instructions use literal constants of various sizes. For
example, BRA (branch) instructions use 16-bit signed lit-
erals to specify the branch destination directly, whereas
the DISI instruction uses a 14-bit unsigned literal field. In
some instructions, such as ADD Acc, the source of an
operand or result is implied by the opcode itself. Certain
operations, such as NOP, do not have any operands.
Addressing Mode Description
File Register Direct The address of the file register is specified explicitly.
Register Direct The contents of a register are accessed directly.
Register Indirect The contents of Wn forms the Effective Address (EA).
Register Indirect Post-Modified The contents of Wn forms the EA. Wn is post-modifie d (incremen ted
or decremented) by a constant value.
Register Indirect Pre-Modified Wn is pre-modified (incremented or decremented) by a signed constant value
to form the EA.
Register Indirect with Register Offset
(Register Indexed) The sum of Wn and Wb forms the EA.
Register Indirect with Literal Offset The sum of Wn and a literal forms the EA.
Note: For the MOV instructions, the addressing
mode specified in the instruction can differ
for the source and destination EA.
However, the 4-bit Wb (Register Offset)
field is shared by both source and
destination (but typically only used by
one).
Note: Not all instructions support all the
addressing modes given above. Individual
instructions may support different subsets
of these addressing modes.

4.4 Interfacing Program and Data
Memory Spaces
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 architecture uses a
24-bit-wide program space and a 16-bit-wide data
space. The architecture is also a modified Harvard
scheme, meaning that data can also be present in th e
program space. To use this data successfully, it must
be accessed in a way that preserves the alignment of
information in both spaces.
Aside from normal execution, the
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 architecture provides two
methods by which program space can be accessed
during operati on:
Using table instructions to access individual bytes
or words anywhere in the program space
Remapping a portion of the program space into
the data space (Program Space Visibility)
Table instructions allow an application to read or write
to small areas of the program memo ry. This capability
makes the method ideal for accessing data tables that
need to be updated periodically. It also allows access
to all bytes of the program word. The remapping
method allows an application to access a large block of
data on a read-only basis, which is ideal for look-ups
from a large table of static data. The application can
only access the least significant word of the program
word.
4.4.1 ADDRESSING PROGRAM SPACE
Since the address ranges for the data and program
spaces are 16 and 24 bits, respectively, a method is
needed to create a 23-bit or 24-bit program address
from 16-bit data registers. The solution depends on the
interface method to be used.
For table operations, the 8-bit Table Page register
(TBLPAG) is used to define a 32K word region within
the program space. This is concatenated with a 16-bit
EA to arrive at a full 24-bit program space address. In
this format, the Most Significant bit (MSb) of TBLPAG
is used to determine if the operation occurs in the user
memory (TBLPAG<7> = 0) or the configuration mem-
ory (TBLPAG<7> = 1).
For remapping operations, the 8-bit Program Space
Visibility register (PSVPAG) is used to define a
16K word page in the program space. When the MSb
of the EA is ‘1’, PSVP AG is concatenated with the lower
15 bits of the EA to form a 23-bit program space
address. Unlike table operatio ns, th is limits remappi ng
operations strictly to the user memory area .
Table 4-36 and Figure 4-6 show how the program EA is
created for table operations and remapping accesses
from the data EA. Here, P<23:0> refers to a program
space word, and D<15:0> refers to a data space word.

4.4.2 DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the program space without going
through data space. The TBLRDH and TBLWTH
instructions are the only method to read or write the
upper 8 bits of a program space word as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to data space addresses.
Program memory can thus be regarded as two 16-bit
wide word address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space that contains the least significant
data word. TBLRDH and TBLWTH access the space that
contains the upper data byte.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from program space.
Both function as either byte or word operati ons.
TBLRDL (Table Read Low):
- In Word mode, this instruction maps the
lower word of the program space
location (P<15:0>) to a data address
(D<15:0>).
- In Byte mode, either the upper or lower byte
of the lower program word is mapped to the
lower byte of a data address. The upper byte
is selected when Byte Select is ‘1’; th e lower
byte is selected when it is ‘0’.
TBLRDH (Table Read High):
- In W ord mode, this instruction maps the entire
upper word of a program address (P<23:16>)
to a data address. The ‘phantom’ byte
(D<15:8>), is always ‘0’.
- In Byte mode, this instruction maps the upper
or lower byte of the program word to D<7:0>
of the data address, in the TBLRDL instruc-
tion. The data is always ‘0’ when the upper
‘phantom’ byte is selected (Byte Select = 1).
Similarly, two table instructions, TBLWTH and TBLWTL,
are used to write individual bytes or words to a pro-
gram space address. The det ails of their operation are
explained in Section 5.0 “Flash Program Memory” .
For all table operations, the area of program memory
space to be accessed is determined by the Table Page
register (TBLPAG). TBLP AG covers the entire program
memory sp ace of the device, in cluding user app lication
and configuration spaces. When TBLPAG<7> = 0, the
table page is located in the user memory space. When
TBLPAG<7> = 1, the page is located in configuration
space.

4.4.3 READING DATA FROM PROGRAM
MEMORY USING PROGRAM SPACE
VISIBILITY
The upper 32 Kbytes of data space may optionally be
mapped into any 16K word page of the program space.
This option provides transparent access to stored
constant data from the data space without the need to
use special instructions, such as TBLRDL/TBLRDH.
Program space access through the data space occurs
if the MSb of the data space EA is ‘1’ and program
space visibility is enabled by setting the PSV bit in the
Core Control register (CORCON<2>). The location of
the program memory space to be mapped into the data
space is determined by the Program Space Visibility
Page register (PSVPAG). This 8-bit register defines
any one of 256 possible pages of 16K words in
program space. In effect, PSVPAG functions as the
upper 8 bits of the program memory address, with the
15 bits of the EA functioning as the lower bits. By
incrementing the PC by 2 for each program memory
word, the lower 15 bits of data sp ace addresses directly
map to the lower 15 bits in the correspondin g p rogram
space addresses.
Data reads to this area add a cycle to the instruction
being executed, since two program memory fetches
are required.
Although each data space address 0x8000 and higher
maps directly into a corresponding program memory
address (see Figure 4-8), only the lower 16 bits of the
24-bit program word are used to contain the data. The
upper 8 bits of any program space location used as
data should be programmed with ‘1111 1111’ or
0000 0000’ to force a NOP. This prevents possible
issues should the area of code ever be accidentally
executed.
For operations that use PSV and are executed outside
a REPEAT loop, the MOV and MOV.D instructions
require one instruction cycle in addition to the specified
execution time. All other instructions require two
instruction cycles in addition to the specified execution
time.
For operations that use PSV, and are executed inside
a REPEAT loop, these instances require two instruction
cycles in addition to the specified execution time of the
instruction:
Execution in the first iteration
Execution in the last iteration
Execution prior to exiting th e loop due to an
interrupt
Execution upon re-entering the loop after an
interrupt is serviced
Any other iteration of the REPEAT loop allows the
instruction using PSV to access data, to execute in a
single cycle.

5.0 FLASH PROGRAM MEMORY
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices contain internal
Flash program memory for storing and executing
application code. The memory is readable, writable and
erasable during normal operation over the entire VDD
range.
Flash memory can be pro grammed in tw o w ays :
In-Circuit Serial Programming™ (ICSP™)
programming capability
Run-T ime Self-Programming (RTSP)
ICSP allows the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices to be serially programmed while in the end
application circuit. This is done with two lines for
programming clock and p rogramming data (one of the
alternate programming pin pairs: PGEC1/PGED1,
PGEC2/PGED2 or PGEC3/PGED3), and three other
lines for power (VDD), ground (VSS) and Master Cl ear
(MCLR). This allows customers to manufacture boards
with unprogrammed devices and then program the
microcontroller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed.
RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
application can write program memory data either in
blocks or ‘rows’ of 64 instructions (192 bytes) at a time
or a single program memory word , and erase p rogram
memory in blocks or ‘pages’ of 512 instructions (1536
bytes) at a time.
5.1 Table Instructions and Flash
Programming
Regardless of the method used, all programming of
Flash memory is done with the table read and table
write instructions. These allow direct read and write
access to the program memory space from the data
memory while the devi ce is in no rmal operating mode.
The 24-bit target address in the program memory is
formed using bits <7:0> of the TBLP AG register and the
Effective Address (EA) from a W register specified in
the table instruction, as shown in Figure 5-1.
The TBLRDL and the TBLWTL instructions are used to
read or write to bits <15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
The TBLRDH and TBLWTH instructions are used to read
or write to bits <23:16> of program memory. TBLRDH
and TBLWTH can also access program memory in Word
or Byte mode.

5.2 RTSP Operation
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 Flash program memory
array is organized into rows of 64 instructions or 192
bytes. RTSP allows the user application to erase a
page of memory, which consists of eight rows (512
instructions) at a time, and to program one row or one
word at a time. Table 28-12 shows typical erase and
programming times. The 8-row erase pages and single
row write rows are edge-ali gned from the begin ning of
program memory, on boundaries of 1536 bytes and
192 bytes, respectively.
The program memory implements holding buffers that
can contain 64 instructions of programming data. Prior
to the actual programming operation, the write data
must be loaded into the buffers sequentially. The
instruction words loaded must always be from a group
of 64 boundary.
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWT instructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register. A total
of 64 TBLWTL and TBLWTH instructio ns are required
to load the instructions.
All of the table write operat ions are single-word writes
(two instruction cycles) because only the buffers are
written. A programming cycle is required for
programming each row.
5.3 Programming Operations
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. The processor stalls (waits) until the
programming operation is finished.
The programming time depe nds on the FRC accuracy
(see Table 28-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4). Use the following
formula to calculate the minimum and maximum values
for the Row Write Time, Page Erase Time, and Word
Write Cycle Time parameters (see Table 28-12).
EQUATION 5-1: PROGRAMMING TIME
For example, if the device is operating at +125°C,
the FRC accuracy will be ±5%. If the TUN<5:0> bits
(see Register 9-4) are set to ‘b111111, the
minimum row write time is equal to Equation 5-2.
EQUATION 5-2: MINIMUM ROW WRITE
TIME
The maximum row write time is equal to Equation 5-3.
EQUATION 5-3: MAXIMUM ROW WRITE
TIME
Setting the WR bit (NVMCON<15>) starts the opera-
tion, and the WR bit is automatically cleared when the
operation is finished.
5.4 Control Registers
Two SFRs are used to read and write the program
Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 5-1) controls which
blocks are to be erased, which memory type is to be
programmed and the start of the programming cycle.
NVMKEY (Register 5-2) is a write-only register that is
used for write protection. T o start a programming or erase
sequence, the user app lication must consecu tively write
0x55 and 0xAA to the NVMKEY register. Refer to
Section 5.3 “Programming Operations” for further
details.

5.4.1 PROGRAMMING ALGORITHM FOR
FLASH PROGRAM MEMORY
Programmers can program one row of p rogram Flash
memory at a time. To do this, it is necessary to erase
the 8-row erase page that contains the desired row.
The general process is:
1. Read eight rows of program memory
(512 in structions) and store in data RAM.
2. Update the program data in RAM with the
desired new data.
3. Erase the block (see Example 5-1):
a) Set the NVMOP bits (NVMCON<3:0>) to
0010’ to configure for block erase. Set the
ERASE (NVMCON<6>) and WREN
(NVMCON<14>) bits.
b) Write the starting address of the p age to be
erased into the TBLPAG and W registers.
c) Writ e 0x55 to NVMKEY.
d) Write 0xAA to NVMKEY.
e) Set the WR bit (NVMCON<15>). The erase
cycle begins and the CPU s t a ll s f or th e d ur a -
tion of the erase cycle. When the erase is
done, the WR bit is cleared automatically.
4. Write the first 64 instructions from data RAM into
the program memory buffers (see Example 5-2).
5. Writ e th e program block to Flash memory:
a) Set the NVMOP bits to ‘0001’ to configure
for row programming. Clear the ERASE bit
and set the WREN bit.
b) Write 0x55 to NVMKEY.
c) Write 0xAA to NVMKEY.
d) Set the WR bit. The programming cycle
begins and the CPU stalls for the duration of
the write cycle. When the write to Flash mem-
ory is done, the WR bit is cleared
automatically.
6. Repeat steps 4 and 5, using the next available
64 instructions from the block in data RAM by
incrementing the value in TBLPAG, until all
512 instructions are written back to Flash memory.
For protection against accidental operations, the write
initiate sequence for NVMKEY must be used to allow
any erase or program operation to proceed. After the
programming command has been executed, the user
application must wait for the programming time until
programming is complete. The two instructions
following the start of the programming sequence
should be NOPs, as shown in Example 5-3.

6.0 RESETS
The Reset module combines all reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
POR: Power-on Reset
BOR: Brown-out Reset
•MCLR
: Master Clear Pin Reset
•SWR: RESET Instruction
WDTO: Watchdog Timer Reset
CM: Configuration Misma tch Reset
TRAPR: Trap Conflict Reset
IOPUWR: Illegal Condition Device Reset
- Illegal Opcode Reset
- Uninitialized W Register Reset
- Security Reset
A simplified block diagram of the Reset module is
shown in Figure 6-1.
Any active source of reset will make the SYSRST
signal active. On system Reset, some of the registers
associated with the CPU a nd pe ripherals a re fo rced to
a known Reset state and some are unaffected.
All types of device Reset sets a corresponding status
bit in the RCON register to indicate the type of Reset
(see Register 6-1).
A POR clears all the bits, except for the POR bit
(RCON<0>), that are set. The user appl ication can set
or clear any bit at any time during code execution. The
RCON bits only serve as status bits. Setting a p articular
Reset status bit in software does not cause a device
Reset to occur.
The RCON register also has other bits associated with
the Watchdog Timer and device power-saving states.
The function of these bits is discussed in other sections
of this manual.

6.1 System Reset
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 family of devices have
two types of Reset:
Cold Reset
Warm Reset
A cold Reset is the result of a Power-on Reset (POR)
or a Brown-out Reset (BOR). On a cold Reset, the
FNOSC configuration bits in the FOSC device
configuration register selects the device clock source.
A warm Reset is the result of all other reset sources,
including the RESET instruction. On warm Reset, the
device will continue to operate from the current clock
source as indicated by the Current Oscillator Selection
bits (COSC<2:0>) in the Oscillator Control register
(OSCCON<14:12>).
The device is kept in a Reset state until the system
power supplies have stabilized at appropriate levels
and the oscillator clock is ready. A description of the
sequence in which this occurs and is shown in
Figure 6-2.

VBOR threshold and the delay TBOR has elapsed. The delay TBOR ensures the voltage regulator output
becomes stable.
3: PWRT Timer: The programmable power-up timer continues to hold the processor in Reset for a specific
period of time (TPWRT) after a BOR. The delay TPWRT ensures that the system power supplies have stabilized
at the appropriate level for full-speed operation. After the delay TPWRT has elapsed, the SYSRST becomes
inactive, which in turn enables the selected oscillator to start generating clock cycles.
4: Oscillator Delay: Th e total delay for the clock to be ready for various clock source selections are given in
Table 6-1. Refer to Section 9.0 “Oscillato r Configuration” for more informat ion.
5: When the oscillator clock is ready, the processor begins execution from location 0x000000. The user
application programs a GOTO instruction at the reset address, which redirects program execution to the
appropriate start-up routine.
6: The Fail-Safe Clock Monitor (FSCM), if enable d, begins to monitor th e system clock when the system clock
is ready and the delay TFSCM elapsed.

6.2 Power-on Reset (POR)
A Power-on Reset (POR) circuit ensures the device is
reset from power-on. The POR circuit is active until
VDD crosses the VPOR threshold and the delay TPOR
has elapsed. The delay TPOR ensures the internal
device bias circuits become stable.
The device supply voltage characteristics must meet
the specified starting voltage and rise rate
requirements to generate the POR. Refer to
Section 28.0 “Electrical Characteristics for details.
The POR status bit (POR) in the Reset Control register
(RCON<0>) is set to indicate the Power-on Reset.
6.2.1 Brown-out Reset (BOR) and
Power-up timer (PWRT)
The on-chip regulator has a Brown-out Reset (BOR)
circuit that resets the device when the VDD is too low
(VDD < VBOR) for proper device operation. The BOR cir-
cuit keeps the device in Reset until VDD crosses VBOR
threshold and the d elay TBOR has elapsed. The delay
TBOR ensures the voltage regulator output becomes
stable.
The Brown-out Reset status bit (BOR) in the Reset
Control register (RCON<1>) is set to indicate the BOR.
The device will not run at full speed after a BOR as the
VDD should rise to acceptable levels for full-speed
operation. The PWRT provides power-up time delay
(TPWRT) to ensure that the system power supplies have
stabilized at the appropriate levels for full-speed
operation before the SYSRST is released.
The power-up timer delay (TPWRT) is programmed by
the Power-on Reset Timer Value Select bits
(FPWRT<2:0>) in the POR Configuration register
(FPOR<2:0>), which provides eight settings (from 0 ms
to 128 ms). Refer to Section 25.0 “Special Features”
for further details.
Figure 6-3 shows the typical brown-out scenarios. The
reset delay (TBOR + TPWRT) is initiated each time VDD
rises above the VBOR trip point
TABLE 6-2: OSCILLATOR DELAY
Symbol Parameter Value
VPOR POR threshold 1.8V nominal
TPOR POR extension time 30 μs maximum
VBOR BOR threshold 2.5V nominal
TBOR BOR extension time 100 μs maximum
TPWRT Programmable power-up time delay 0-128 ms nominal
TFSCM Fail-Safe Clock Monitor Delay 900 μs maximum
Note: When the device exits the Reset
condition (begins normal operation), the
device operating parameters (voltage,
frequency, temperature, etc.) must be
within their operating ranges, otherwise
the device may not function correctly.
The user application must ensure that
the delay between the time power is
first applied, and the time SYSRST
becomes inactive, is long enough to get
all operating parameters within
specification.

FIGURE 6-3: BROWN-OUT SITUATIONS
6.3 External Reset (EXTR)
The external Reset i s generated by driving the MCLR
pin low . The MCLR pin is a Schmitt trigger input with an
additional glitch filter . Reset pulses that are longer than
the minimum pulse width will generate a Re set. Refer
to Section 28.0 “Electrical Characteristics” for
minimum pulse width specifications. The External
Reset (MCLR) Pin (EXTR) bit in the Reset Control
(RCON) register is set to indicate the MCLR Reset.
6.3.0.1 EXTERNAL SUPERVISORY CIRCUIT
Many systems have external supervisory circuits that
generate reset signals to reset multiple devices in the
system. This external Reset signal can be directly con-
nected to the MCLR pin to reset the device when the
rest of system is Reset.
6.3.0.2 INTERNAL SUPERVISORY CIRCUIT
When using the internal power supervisory circuit to
reset the device, the external reset pin (MCLR ) shoul d
be tied directly or resistively to VDD. In this case, the
MCLR pin will not be used to generate a Reset. The
external reset pin (MCLR) does not have an internal
pull-up and must not be left unconnected.
6.4 Software RESET Instruction (SWR)
Whenever the RESET instruction is executed, the
device will assert SYSRST, placing the device in a
special Reset state. This Reset state will not re-
initialize the clock. The clock source in ef fect prior to the
RESET instruction will remain. SYSRST is released at
the next instruction cycle, and the reset vector fetch will
commence.
The Software Reset (Instruction) Flag bit (SWR) in the
Reset Control register (RCON<6>) is set to indicate
the software Reset.
6.5 Watchdog Time-out Reset (WDTO)
Whenever a Watchdog time-out occurs, the device will
asynchronously assert SYSRST. The clock source will
remain unchanged. A WDT time-out during Sleep or
Idle mode will wake-up the processor, but will not reset
the processor.
The Watchdog Timer Time-out Flag bit (WDTO) in the
Reset Control register (RCON<4>) is set to indicate
the Watchdog Reset. Refer to Section 25.4
“Watchdog Timer (WDT)” for more information on
Watchdog Reset.
6.6 Trap Conflict Reset
If a lower-priority hard trap occu rs while a higher-prior-
ity trap is being processed, a hard trap conflict Reset
occurs. The hard traps include exceptions of priority
level 13 through level 15, inclusive. The address error
(level 13) and oscillator error (level 14) traps fall into
this category.
The Trap Reset Flag bit (TRAPR) in the Reset Control
register (RCON<15>) is set to indicate the T rap Conflict
Reset. Refer to Section 7.0 “Interrupt Controller” for
more information on trap conflict Resets.

6.7 Configuration Mismatch Reset
To maintain the integrity of the peripheral pin select
control registers, they are constantly monitored with
shadow registers in hardware. If an unexpected
change in any of the registers occur (such as cell dis-
turbances caused by ESD or other external events), a
configuration mismatch Reset occurs.
The Config uratio n Mismat ch Flag bit (CM) i n the Re set
Control register (RCON<9>) is set to indicate the
configuration mismatch Reset. Refer to Section 11.0
“I/O Ports” for more information on the configuration
mismatch Reset.
6.8 Illegal Condition Device Reset
An illegal condition device Reset occurs due to the
following sources:
Illegal Opcode Reset
Uninitialized W Registe r Reset
Security Reset
The Illegal Opcode or Uninitialized W Access Reset
Flag bit (IOPUWR) in the Reset Control register
(RCON<14>) is set to indicate the illegal condition
device Re se t.
6.8.0.1 ILLEGAL OPCODE RESET
A device Reset is generated if the device attempts to
execute an illegal opcode value that is fetched from
program memory.
The illegal opcode Reset function can prevent the
device from executing program memory sections that
are used to store constant data. To take advantage of
the illegal opcode Re set, use only the lower 16 bits of
each program memory section to store the data values.
The upper 8 bits should be programmed with 3Fh,
which is an illegal opco de value.
6.8.0.2 UNINITIALIZED W REGISTER
RESET
Any attempts to use the uninitialized W re gister as an
address pointer will Reset the device. The W register
array (with the exception of W1 5) is cleared during all
resets and is considered uninitialized until written to.
6.8.0.3 SECURITY RESET
If a Program Flow Change (PFC) or Vector Flow
Change (VFC) targets a restricted location in a
protected segment (Boot and Secure Segment), that
operation will cause a security Reset.
The PFC occurs when the Program Counter is
reloaded as a result of a Call, Jump, Co mputed Jump,
Return, Return from Subroutine, or other form of
branch instruction.
The VFC occurs when the Program Counter is
reloaded with an Interrupt or Trap vector.
Refer to Section 25.8 “Code Protection and
CodeGuard™ Security” for more information on
Security Reset.
6.9 Using the RCON Status Bits
The user application can read the Reset Control regis-
ter (RCON) after any device Reset to determine the
cause of the reset.
Table 6-3 provides a summary of the reset flag bit
operation.
TABLE 6-3: RESET FLAG BIT OPERATION
Note: The configuration mismatch feature and
associated reset flag is not available on all
devices.
Note: The status bits in the RCON register
should be cleared after they are read so
that the next RCON reg ister value after a
device Reset will be meaningful.

PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
7.0 INTERRUPT CONTROLLER
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 interrupt controller
reduces the numerous peripheral interrupt request sig-
nals to a single interrupt request signal to the
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 CPU.
The interrupt controller has the following features:
Up to eight processor exceptions and software
traps
Eight user-selectable priority levels
Interrupt Vector Table (IVT) with up to 118 vectors
A unique vector for each interrupt or exception
source
Fixed priority within a specified user priority level
Alternate Interrupt Vector Table (AIVT) for debug
support
Fixed interrupt entry and return latencies
7.1 Interrupt Vector Table
The Interrupt Vector Table (IVT), shown in Figure 7-1,
resides in program memory, starting at location
000004h. The IVT contains 126 vectors consisting of
eight nonmaskable trap vectors plus up to 118 sources
of interrupt. In general, each interrupt source has its
own vector . Each interrupt vector contains a 24 bit wide
address. The value programmed into each interrupt
vector location is the starting address of the associated
Interrupt Service Routine (ISR).
Interrupt vectors are prioritized in terms of their natural
priority. This priority is linked to their position in the
vector table. Lower addresses generally have a higher
natural priority. For example, the interrupt associated
with vector 0 takes priority over interrupts at any other
vector address.
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices implement up to 45
unique interrupts and five nonmaskable traps. These
are summarized in Table 7-1.
7.1.1 ALTERNATE INTERRUPT VECTOR
TABLE
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT, as shown in Figure 7-1. Access to the
AIVT is provided by the ALTIVT control bit
(INTCON2<15>). If the ALTIVT bit is set, all interrupt
and exception processes use the alternate vectors
instead of the default vectors. The alternate vectors are
organized in the same manner as the default vectors.
The AIVT supports debugging by providing a means to
switch between an application and a support
environment without requiring the interrupt vectors to
be reprogrammed. This feature also enables switching
between applications for evaluation of different
software algorithms at run time. If the AIVT is not
needed, the AIVT should be programmed with the
same addresses used in the IVT.
7.2 Reset Sequence
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 device clears its
registers in response to a Reset, which forces the PC
to zero. The microcontroller then begins program
execution at location 0x000000. A GOTO instruction at
the Reset address can redirect program execution to
the appropriate start-up routine.
Note 1: This data sheet summarizes the features
of the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 families of
devices. It is not intended to be a compre-
hensive reference source. To comple-
ment the information in this data sheet,
refer to Section 32. “Interrupts
(Part III)” (DS70214) of
the”dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip website (www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Note: Any unimplemented or unused vector
locations in the IVT and AIVT should be
programmed with the address of a default
interrupt handler routine that contains a
RESET instruction.

PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
7.3 Interrupt Control and Status
Registers
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices implement a total of
30 registers for the interrupt controller:
INTCON1
INTCON2
•IFSx
•IECx
•IPCx
•INTTREG
7.3.1 INTCON1 AND INTCON2
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the
Interrupt Nesting Disable (NSTDIS) bit as well as the
control and status flags for the processor trap sources.
The INTCON2 register controls the external interrupt
request signal behavior and the use of the Alternate
Interrupt Vector Table.
7.3.2 IFSx
The IFS registers maintain all of the interrupt request
flags. Each source of interrupt has a status bit, which is
set by the respective peripherals or external signal and
is cleared via software.
7.3.3 IECx
The IEC registers maintain all of the interrupt enable
bits. These control bits are used to individually enabl e
interrupts from the peripherals or external signals.
7.3.4 IPCx
The IPC registers are used to set the interrupt priority
level for each source of interrupt. Each user interrupt
source can be assigned to one of eight priority levels.
7.3.5 INTTREG
The INTTREG register contains the associated
interrupt vector number and the new CPU interrupt
priority level, which are latched into vector number
(VECNUM<6:0>) and Interrupt level (ILR<3:0>) bit
fields in the INTTREG register. The new interrupt
priority level is the priority of the pending interrupt.
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the same sequence that they are
listed in Table 7-1. For example, the INT0 (External
Interrupt 0) is shown as h aving vector nu mber 8 and a
natural order priority of 0. Thus, the INT0IF bit is found
in IFS0<0>, the INT0IE bit in IEC0<0>, and the INT0IP
bits in the first position of IPC0 (IPC0<2:0>).
7.3.6 STATUS/CONTROL REGISTERS
Although they are not specifically part of the interrupt
control hardware, two of the CPU Control registers
contain bits that control interrupt functionality.
The CPU STATUS registe r, SR, contains the
IPL<2:0> bits (SR<7:5>). These bits indicate the
current CPU interrupt priority level. The user
software can change the current CPU priority
level by writing to the IPL bits.
The CORCON register contains the IPL3 bit
which, together with IPL<2:0>, also indicates the
current CPU priority level. IPL3 is a read-only bit
so that trap events cannot be masked by the user
software.
All Interrupt registers are described in Register 7-1
through Register 7-29.

7.4.1 INITIALIZATION
To configure an interrupt source at initialization:
1. Set the NSTDIS bit (INTCON1<15>) if nested
interrupts are not desired.
2. Select the user-assigned priority level for the
interrupt source by writing the control bits in th e
appropriate IPCx register. The priority level
depends on the sp ecific application and type of
interrupt source. If multiple priority levels are not
desired, the IPCx register control bits for all
enabled interrupt sources can be programmed
to the same non-zero value.
3. Clear the interrupt flag status bit associated with
the peripheral in the associated IFSx register.
4. Enable the interrupt sour ce by setting the inter-
rupt enable control bit associated with the
source in the appropriate IECx register.
7.4.2 INTERRUPT SERVICE ROUTINE
The method used to declare an ISR and initialize the
IVT with the correct vector address depends on the
programming language (C or assembler) and the
language development tool suite used to develop the
application.
In general, the user application must clear the interrupt
flag in the appropriate IFSx register for the source of
interrupt that the ISR handles. Otherwise, the p rogram
re-enters the ISR immediately after exiting the routine.
If the ISR is coded in assembly language, it must be
terminated using a RETFIE instruction to unstack the
saved PC value, SRL value and old CPU priority level.
7.4.3 TRAP SERVICE ROUTINE
A Trap Service Routine (TSR) is coded like an ISR,
except that the appropriate trap status flag in the
INTCON1 register must be cleared to avoid re-entry
into the TSR.
7.4.4 INTERRUPT DISABLE
All user interrupts can be disabled using this
procedure:
1. Push the current SR value onto the software
stack using the PUSH instruction.
2. Force the CPU to priority level 7 by inclusive
ORing the value 0xOE with SRL.
To enable user interrupts, the POP instruction can be
used to restore the previous SR value.
The DISI instruction provides a convenient way to
disable interrupts of priority levels 1-6 for a fixed period
of time. Level 7 interrupt sources are not disabled by
the DISI instruction.
Note: At a device Reset, the IPCx registers are
initialized such that all user interrupt
sources are assigned to priority level 4. Note: Only user interrupts with a priority level of
7 or lower can be disab led. Trap sources
(level 8-level 15) cannot be disabled.

8.0 DIRECT MEMORY ACCESS
(DMA) Direct Memory Access (DMA) is a very efficient
mechanism of copying data between pe ripheral SFRs
(e.g., UART Receive register, Input Capture 1 buffer),
and buffers or variables stored in RAM, with minimal
CPU intervention. The DMA controller can
automatically copy entire blocks of data without
requiring the user software to read or write the
peripheral Special Function Registers (SFRs) every
time a peripheral interru pt occurs. The DMA controller
uses a dedicated bus for data transfers and therefore,
does not steal cycles from the code execution flow of
the CPU. To exploit the DMA capability, the
corresponding user buffers or variables must be
located in DMA RAM.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 peripherals that can
utilize DMA are listed in Table 8-1.
Note 1: This data sheet summarizes the features
of the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 families of
devices. It is not intended to be a compre-
hensive reference source. To comple-
ment the information in this data sheet,

The DMA controller features eight identical data
transfer chann el s.
Each channel has its own set of control and status
registers. Each DMA channel can be configured to
copy data either from buffers stored in dual port DMA
RAM to peripheral SFRs, or from peripheral SFRs to
buffers in DMA RAM.
The DMA controller supports the following features:
Eight DMA channels
Register Indirect with Post-incremen t Addressing
mode
Register Indirect without Post-increment
Addressing mode
Peripheral Indirect Addressi ng mode (peripheral
generates destination addre ss)
CPU interrupt after half or full block transfer
complete
Byte or word trans fe rs
Fixed priority channel arbitration
Manual (software) or Automatic (peripheral DMA
requests) transfer initiation
One-Shot or Auto-Repeat block transfer modes
Ping-Pong mode (automatic switch between two
DPSRAM start addresses after each block
transfer complete)
DMA request for each channel can be selected
from any supported interrupt source
Debug support features
For each DMA channel, a DMA interrupt request is
generated when a block transfer is complete.
Alternatively, an interrupt can be generated when half of
the block has been filled.

8.1 DMAC Registers
Each DMAC Channel x (x = 0, 1, 2, 3, 4, 5, 6 or 7)
contains the following registers:
A 16-bit DMA Channel Control register
(DMAxCON)
A 16-bit DMA Channel IRQ Select register
(DMAxREQ)
A 16-bit DMA RAM Primary S tart Address register
(DMAxSTA)
A 16-bit DMA RAM Secondary St art Address
register (DMAxSTB)
A 16-bit DMA Peripheral Address register
(DMAxPAD)
A 10-bit DMA Transfer Count register (DMAxCNT)
An additional pair of status registers, DMACS0 and
DMACS1, are common to all DMAC channels.
DMACS0 contains the DMA RAM and SFR write
collision flags, XWCOLx and PWCOLx, respectively.
DMACS1 indicates DMA channel and Ping-Pong mode
status.
The DMAxCON, DMAxREQ, DMAxPAD and
DMAxCNT are all conventional read/write registers.
Reads of DMAxSTA or DMAxSTB reads the contents
of the DMA RAM Address register. Writes to
DMAxSTA or DMAxSTB write to the registers. This
allows the user to determine the DMA buffer pointer
value (address) at any time.
The interrupt flags (DMAxIF) are located in an IFSx
register in the interrupt controller. The corresponding
interrupt enable control bits (DMAxIE) are located in
an IECx register in the interrupt controller, and the
corresponding interrupt priority control bits (DMAxIP)
are located in an IPCx register in the interrupt
controller.

9.1 CPU Clocking System
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices provide seven
system clock options:
Fast RC (FRC) Oscillator
FRC Oscillator with Phase Locked Loop (PLL)
Primary (XT, HS or EC) Oscillator
Primary Oscillator with PLL
Secondary (LP) Oscillator
Low-Power RC (LPRC) Oscillator
FRC Oscillator with postscaler
9.1.1 SYSTEM CLOCK SOURCES
The Fast RC (FRC) internal oscillator runs at a nominal
frequency of 7.37 MHz. User software can tune the
FRC frequency. User software can optio nal ly specify a
factor (ranging from 1:2 to 1:256) by which the FRC
clock frequency is divided. This factor is selected using
the FRCDIV<2:0> (CLKDIV<10:8>) bits.
The primary oscillator can u se one of the following as
its clock source:
Crystal (XT): Cryst als and ceramic resonators in
the range of 3 MHz to 10 MHz. The crystal is
connected to the OSC1 and OSC2 pins.
High-Speed Crystal (HS): Cryst als in the range of
10 MHz to 40 MHz. The crystal is connected to
the OSC1 and OSC2 pins.
External Clock (EC): External clock signal is
directly applied to the OSC1 pin.
The secondary (LP) oscillator is designed for low power
and uses a 32.768 kHz crystal or ceramic resonator.
The LP oscillator uses the SOSCI and SOSCO pins.
The Low-Power RC (LPRC) internal oscIllator runs at a
nominal frequency of 32.76 8 kHz. It is also used as a
reference clock by the Watchdog Timer (WDT) and
Fail-Safe Clock Monitor (FSCM).
The clock signals generated by the FRC and primary
oscillators can be optiona lly applied to an on -chip PLL
to provide a wide range of output frequencies for device
operation. PLL configuration is described in
Section 9.1.3 “PLL Configuration”.
The FRC frequency depends on the FRC accuracy
(see Table 28-19) and the value of the FRC Oscillator
Tuning register (see Register 9-4).
9.1.2 SYSTEM CLOCK SELECTION
The oscillator source used at a device Power-on
Reset event is selected using Configuration bit
settings. The oscillator Configuration bit settings are
located in the Configuration registers in the program
memory. (Refer to Section 25.1 “Configuration
Bits” for further details.) The Initial Oscillator
Selection Configuration bits, FNOSC<2:0>
(FOSCSEL<2:0>), and the Primary Oscillator Mode
Select Configuration bits, POSCMD<1:0>
(FOSC<1:0>), select the oscillato r source that is used
at a Power-on Reset. The FRC primary oscillator is
the default (unprogrammed) selection.
The Configuration bits allow users to choose among 12
different clock modes, shown in Table 9-1.
The output of the oscilla tor (or the output of the PLL if
a PLL mode has been selected) FOSC is divided by 2 to
generate the device instruction clock (FCY) and the
peripheral clock time base (FP). FCY defines the
operating speed of the device, and speeds up to 40
MHz are supported by the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
architecture.
Instruction execution speed or device operating
frequency, FCY, is given by:

9.1.3 PLL CONFIGUR ATION
The primary oscillator and internal FRC oscillator can
optionally use an on-chip PL L to obtain higher speeds
of operation. The PLL provides significant flexibility in
selecting the device op erating spee d. A block dia gram
of the PLL is shown in Figure 9-2.
The output of the primary oscillator or FRC, denoted as
‘FIN’, is divided down by a prescale factor (N1) of 2, 3,
... or 33 before being provided to the PLL’s Voltage
Controlled Oscillator (VCO). The input to the VCO must
be selected in the range of 0.8 MHz to 8 MHz. The
prescale factor ‘N1’ is selected using the
PLLPRE<4:0> bits (CLKDIV<4:0>).
The PLL Feedback Divisor, selected using the
PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor ‘M’,
by which the input to the VCO is multiplied. This factor
must be selected such that the resulting VCO output
frequency is in the range of 100 MHz to 200 MHz.
The VCO output is further divided by a postscale factor
‘N2’. This factor is selecte d using the PLLPOST<1:0>
bits (CLKDIV<7:6>). ‘N2’ can be either 2, 4 or 8, and
must be selected such that the PLL output frequency
(FOSC) is in the range of 12.5 MHz to 80 MHz, which
generates device operating speeds of 6.25-40 MIPS.
For a primary oscillator or FRC oscillator, output ‘F IN’,
the PLL output ‘FOSC’ is given by:
EQUATION 9-2: FOSC CALCULATION
For example, suppose a 10 MHz crystal is being used
with the selected oscillator mode of XT with PLL.
If PLLPRE<4:0> = 0, then N1 = 2. This yields a
VCO input of 10/2 = 5 MHz, which is within the
acceptable range of 0.8-8 MHz.
If PLLDIV<8:0> = 0x1E, then M = 32. This yields a
VCO output of 5 x 32 = 160 MHz, which is within
the 100-200 MHz ranged needed.
If PLLPOST<1:0> = 0, then N2 = 2. This provides
a Fosc of 160/2 = 80 MHz. The resultant device
operating speed is 80/2 = 40 MIPS.

9.2 Clock Switching Operation
Applications are free to switch among any of the four
clock sources (Primary, LP, FRC and LPRC) under
software control at any time . To limit the possible sid e
effects of this flexibility, PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices have a safeguard lock built into the switch
process.
9.2.1 ENABLING CLOCK SWITCHING
To enable clock switching, th e FCKSM1 Configuration
bit in the Configuration register must be programmed to
0’. (Refer to Section 25.1 “Configuration Bits” for
further details.) If the FCKSM1 Configuration bit is
unprogrammed (‘1’), the clock switching function and
FSCM function are disabled. This is the default setting.
The NOSC<2:0> control bits (OSCCON<10:8>) do not
control the clock selection when clock switching is
disabled. However, the COSC<2:0> bits (OSC-
CON<14:12>) refle ct the clock source selected by the
FNOSC<2:0> Configuration bits FOSCSEL<2:0>.
The OSWEN control bit (OSCCON<0>) has no effect
when clock switching is disabled. It is he ld at 0’ at all
times.
9.2.2 OSCILLATOR SWITCHING SEQUENCE
Performing a clock switch requires this basic
sequence:
1. If required, read the COSC<2:0> bits to deter-
mine the current oscillator source.
2. Perform the unl ock sequence to allow a write to
the OSCCON register high byte.
3. Write the appropriate value to the NOSC<2:0>
control bits for the new oscillator source.
4. Perform the unl ock sequence to allow a write to
the OSCCON register low byte.
5. Set the OSWEN bit to initiate the oscillator
switch.
After the basic sequence is completed, the system
clock hardware responds automatically as follows:
1. The clock switching hardware compares the
COSC<2:0> status bits with the new value of the
NOSC<2:0> control bits. If they are the same,
the clock switch is a redundant operation. In this
case, the OSWEN bit is cleared automatically
and the clock switch is aborted.
2. If a valid clock switch has been initiated, the
LOCK (OSCCON<5>) and the CF
(OSCCON<3>) status bits are cleared.
3. The new oscillator is turned on by the hardware
if it is not currently running. If a crystal oscillator
must be turned on, th e hardware waits until the
Oscillator Start-up Timer (OST) expires. If the
new source is using the PLL, the hardware waits
until a PLL lock is detected (LOCK = 1).
4. The hardware waits for 10 clock cycles from the
new clock source and then performs the clock
switch.
5. The hardware clears the OSWEN bit to indicate a
successful clock transition. In addition, the NOSC
bit values are transferred to the COSC<2:0>
status bits .
6. The old clock source is turned off at this time,
with the exception of LPRC (if WDT or FSCM
are enabled) or LP (if LPOSCEN remains set).
9.3 Fail-Safe Clock Monitor (FSCM)
The Fail-Safe Clock Monitor (FSCM) allows the device
to continue to operate even in the event of an oscillator
failure. The FSCM function is enabled by programming.
If the FSCM function is enabled, the LPRC internal
oscillator runs at all times (except during Sleep mode)
and is not subject to control by the Watchdog Timer.
If an oscillator fails, the FSCM generates a clock failure
trap event and switches the system clock over to the
FRC oscillator. Then the application program can either
attempt to restart the oscillator or execute a controll ed
shutdown. The trap can be treated as a warm Reset by
simply loading the Reset address into the oscillator fail
trap vector.
If the PLL multiplier is used to scale the system clock,
the internal FRC is also multiplied by the same factor
on clock failure. Essentially, the device switches to
FRC with PLL on a clock failure.
Note: Primary Oscillator mode has three different
submodes (XT, HS and EC), which are
determined by the POSCMD<1:0> C onfig-
uration bits. While an application can
switch to and from Primary Oscillator
mode in software, it cannot switch among
the different primary submodes without
reprogramming the device.
Note 1: The processor continues to execute code
throughout the clock switching sequence.
Timing-sensitive code should not be
executed during this time.
2: Direct clock switches between any pri-
mary oscillator mode with PLL and
FRCPLL mode are not permitted. This
applies to clock switches in either direc-
tion. In these instances, the application
must switch to FRC mode as a transition
clock source between the two PLL modes.

(Part III)” (DS70308) in the “dsPIC33F/
PIC24H Family Reference Manual” for
details.

PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
10.0 POWER-SAVING FEATURES
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices provide the
ability to manage power consumption by selectively
managing clocking to the CPU and the peripherals. In
general, a lower clock frequency and a reduction in the
number of circuits being clocked constitutes lower
consumed power. PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices can manage power consumption in four ways:
Clock frequency
Instruction-based Sleep and Idle modes
Software-controlled Doze mode
Selective peripheral control in software
Combinations of these methods can be used to selec-
tively tailor an application’s power consumption while
still maintaining critical application features, such as
timing-sensitive communications.
10.1 Clock Frequency and Clock
Switching
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices allow a wide range of
clock frequencies to be selected under application
control. If the system clock configuration is not locked,
users can choose low-power or high-precision
oscillators by simply changing the NOSC bits
(OSCCON<10:8>). The process of changing a system
clock during operation, as well as limitations to the
process, are discussed in more detail in Section 9.0
“Oscillator Configuration” .
10.2 Instruction-Based Power-Saving
Modes
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices have two special
power-saving modes that are entered through the
execution of a special PWRSAV instruction. Sleep mode
stops clock operation and halts all code execution. Idle
mode halts the CPU and code execution, but allows
peripheral modules to continue operation. The
assembler syntax of the PWRSAV instruction is shown in
Example 10-1.
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these mo des, it is said to wake up.
10.2.1 SLEEP MODE
The following occur in Sleep mode:
The system clock source is shut down. If an
on-chip oscillator is used, it is turned off.
The device current consumption is reduce d to a
minimum, provided that no I/O pin is sourcing
current.
The Fail-Safe Clock Monitor does not operate,
since the system clock source is disabled.
The LPRC clock continues to run in Sleep mode if
the WDT is enabled.
The WDT, if enabled, is automatically cleared
prior to entering Sleep mode.
Some device features or peripherals can contin ue
to operate. This includes items such as the input
change notification on the I/O ports, or peripherals
that use an external clock input.
Any peripheral that requires the system clock
source for its operation is disabled.
The device wakes up from Sleep mode on any of the
these events:
Any interrupt source that is individually enabled
Any form of device Reset
A WDT time-out
On wake-up from Sleep mode, the processor restarts
with the same clock source that was active when Sleep
mode was entered.

10.2.2 IDLE MODE
The following occur in Idle mode:
The CPU stops executing instructions.
The WDT is automatically cleared.
The system clock source remains active. By
default, all peripheral modules continue to operate
normally from the system clock source, but can
also be selectively disabled (see Section 10.4
“Peripheral Module Disable”).
If the WDT or FSCM is enabled, the LPRC also
remains active.
The device wakes from Idle mode on any of these
events:
Any interrupt that is individually enabled
Any device Reset
A WDT time-out
On wake-up from Idle mode, the clock is reapplied to
the CPU and instruction execution will begin (2 to 4
cycles later), starting with the instruction following the
PWRSAV instruction, or the first instruction in the ISR.
10.2.3 INTERRUPTS COINCIDENT WITH
POWER SAVE INSTRUCTIONS
Any interrupt that coincides with the execution of a
PWRSAV instruction is held off until entry into Sleep or
Idle mode has completed. The device then wakes up
from Sleep or Idle mode.
10.3 Doze Mode
The preferred strategies for reducing power
consumption are changing clock speed and invoking
one of the power-saving modes. In some
circumst ances, this cannot be pr actical. For example, it
may be necessary for an application to maintain
uninterrupted synchronous communication, even while
it is doing nothing else. Reducing system clock spee d
can introduce communication errors, while using a
power-saving mode can stop communications
completely.
Doze mode is a simple and effective alternative method
to reduce power consumption while the device is still
executing code. In this mode, the system clock
continues to operate from the same source and at the
same speed. Peripheral modules continue to be
clocked at the same speed, while the CPU clock speed
is reduced. Synchronization between the two clock
domains is maintained, allowing the peripherals to
access the SFRs while the CPU executes code at a
slower rate.
Doze mode is enabled by setting the DOZEN bit
(CLKDIV<11>). The ratio between peripheral and core
clock speed is determined by the DOZE<2:0> bits
(CLKDIV<14:12>). There are eight possible
configurations, from 1:1 to 1:128, with 1:1 being the
default setting.
Programs can use Doze mode to selectively reduce
power consumption in event-driven applications. This
allows clock-sensitive functions, such as synchronous
communications, to continu e witho ut interruption while
the CPU idles, waiting for something to invoke an
interrupt routine. An automatic return to full-speed CPU
operation on interrupts can be enabled by setting the
ROI bit (CLKDIV<15>). By default, interrupt events
have no effect on Doze mode operation.
For example, suppose the device is operating at
20 MIPS and the ECAN module has been configured
for 500 kbps based on this device operating speed. If
the device is placed in Doze mode with a clock
frequency ratio of 1:4, the ECAN mod ule continues to
communicate at the required bit rate of 500 kbps, but
the CPU now starts executing instructions at a
frequency of 5 MIPS.
10.4 Peripheral Module Disable
The Peripheral Module Disable (PMD) registers
provide a method to disable a peripheral module by
stopping all clock sources supplied to that module.
When a peripheral is disabled using the appropriate
PMD control bit, the peripheral is in a minimum po wer
consumption state. The control and status registers
associated with the peripheral are also disabled, so
writes to those registers do not have effect and read
values are invalid.
A peripheral module is enabled only if both the
associated bit in the PMD register is cleared and the
peripheral is supported by the specific PIC MCU
variant. If the peripheral is present in the device, it is
enabled in the PMD registe r by default.
Note: If a PMD bit is set, the corresponding
module is disabled after a delay of one
instruction cycle. Similarly, if a PMD bit is
cleared, the corresponding module is
enabled after a delay of one instruction
cycle (assuming the module control regis-
ters are already configured to enable
module operation).

11.0 I/O PORTS
All of the device pins (except VDD, VSS, MCLR and
OSC1/CLKI) are shared among the peripherals and the
parallel I/O ports. All I/O input ports feature Schmitt
Trigger inputs for improved noise immunity.
11.1 Parallel I/O (PIO) Ports
Generally a parallel I/O port that shares a pin with a
peripheral is subservient to the peripheral. The
peripheral’s output buffer data and control signals are
provided to a pair of multiplexers. The multiplexers
select whether the peripheral or the associated port
has ownership of the output data and control signals of
the I/O pin. The logic also prevents “loop through”, in
which a port’s digital output can drive the input of a
peripheral that shares the same pin. Figure 11-1 shows
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.
When a peripheral is enabled and the peripheral is
actively driving an associated pin, the use of the pin as
a general purpose output pin is disabled. The I/O pin
can be read, but the output driver for the parallel port bit
is disabled. If a peripheral is enabled, but the peripheral
is not actively driving a pin, that pin can be driven by a
port.
All port pins have three registers directly associated
with their operation as digital I/O. The data direction
register (TRISx) determines whether the pin is an input
or an output. If the data direction bit is a ‘1’, then the pin
is an input. All port pins are defined as inputs after a
Reset. Reads from the latch (LATx) read the latch.
Writes to the latch write the latch. Reads from the port
(PORTx) read the port pins, while writes to the port pins
write the latch.
Any bit and its associated data and control registers
that are not valid for a particular device is disabled.
This means the corresponding LATx and TRISx
registers and the port pin are read as zeros.
When a pin is shared with another peripheral or
function that is defined as an input only, it is
nevertheless regarded as a dedicated port because
there is no other competing source of outputs.

11.2 Open-Drain Configuration
In addition to the PORT, LAT and TRIS registers for
data control, some port pins can also be individually
configured for either digital or open-drain output. This
is controlled by the Open-Drain Control register,
ODCx, associated with each port. Setting any of the
bits configures the corresponding pin to act as an
open-drain output.
The open-drain feature allows the generation of
outputs higher than VDD (e.g., 5V) on any desired 5V
tolerant pins by using external pull-up resistors. The
maximum open-drain voltage allowed is the same as
the maximum VIH specification.
See Pin Diagrams for the available pins and their
functionality.
11.3 Configuring Analog Port Pins
The AD1PCFGL and TRIS registers control the opera-
tion of the analog-to-digital (A/D) port pins. The port
pins that are to function as analog inputs must have
their corresponding TRIS bit set (i nput). If the TRIS bit
is cleared (output), the digital output level (VOH or VOL)
is converted.
The AD1PCFGL register has a default value of 0x0000;
therefore, all pins that share ANx functions are analo g
(not digital) by default.
When the PORT register is read, all pins configured as
analog input channels are read as cleared (a low level).
Pins configured as digital inputs do not convert an
analog input. Analog levels on any pin defined as a
digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.
11.4 I/O Port Write/Read Timing
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically this instruction
would be an NOP, as shown in Example 11-1.
11.5 Input Change Notification
The input change notification function of the I/O ports
allows the PIC24HJ32GP302/304, PIC24HJ64GPX02/
X04 and PIC24HJ128GPX02/X04 d evices to generate
interrupt requests to the processor in response to a
change-of-state on selected input pins. This feature
can detect input change-of-states even in Sleep mode,
when the clocks are disabled. Depending on the device
pin count, up to 21 external signals (CNx pin) can be
selected (enabled) for generating an interrupt request
on a change-of-state.
Four control registers are associated with the CN mod-
ule. The CNEN1 and CNEN2 registers contain the
interrupt enable control bits for each of the CN input
pins. Setting any of these bits enables a CN interrupt
for the corresponding pins.
Each CN pin also has a weak pull-up connected to it.
The pull-ups act as a current source connected to the
pin, and eliminate the need for external resistors when
push-button or keypad devices are connected. The
pull-ups are enabled separately using the CNPU1 and
CNPU2 registers, which contain the control bits for
each of the CN pins. Setting any of the control bits
enables the weak pull-ups for the corresponding pins.
EXAMPLE 11-1: PORT WRITE/READ EXAMPLE
Note: Pull-ups on change notification pins
should always be disabled when the port
pin is configured as a digital output.

11.6 Peripheral Pin Select
Peripheral pin select configuration enables peripheral
set selection and placement on a wide range of I/O
pins. By increasing the pinout options available on a
particular device, programmers can better tailor the
microcontroller to their entire application, rather than
trimming the application to fit the device .
The peripheral pin select configuration feature
operates over a fixed subset of digital I/O pins.
Programmers can independently map the inpu t and/or
output of most digital peripherals to any one of these
I/O pins. Peripheral pin select is performed in
software, and generally does not require the device to
be reprogrammed. Hardware safe guards are included
that prevent accidental or spurious changes to the
peripheral mapping, once it has been established.
11.6.1 AVAILABLE PINS
The peripheral pin select feature is used with a range
of up to 26 pins. The number of available pins depends
on the particular device and its pin count. Pins that
support the peripheral pin select feature include the
designation “RPn” in their full pin designation, where
“RP” designates a remappable peripheral and “n” is the
remappable pin number.
11.6.2 CONTROLLING PERIPHERAL PIN
SELECT
Peripheral pin select features are controlled through
two sets of special function registers: one to map
peripheral inputs, and another one to map outputs.
Because they are separately controlled, a particular
peripheral’s input and output (if the peripheral has both)
can be placed on any selectable function pin without
constraint.
The association of a pe ripheral to a peripheral select-
able pin is handled in two different ways, depending on
whether an input or output is being mappe d.
11.6.2.1 Input Mapping
The inputs of the peripheral pin select options are
mapped on the basis of the peripheral. A control
register associated w ith a peripheral dictates the pin it
is mapped to. The RPINRx registers are used to
configure periphera l input mapping (see Register 11-1
through Register 11-14). Each register contains sets of
5-bit fields, with each set associated with one of the
remappable peripherals. Programming a given
peripheral’s bit field with an appropriate 5-bit value
maps the RPn pin with that value to that peripheral.
For any given device, the valid range of values for any
bit field corresponds to the maximum number of
peripheral pin selections supported by the device.
Figure 11-2 illustrates remappable pin selection for
U1RX input.
FIGURE 11-2: REMAP PABLE MUX
INPUT FOR U1RX
Note: For input mapping only , the Peripheral Pin
Select (PPS) functionality does not have
priority over the TRISx settings. There-
fore, when configuring the RPx pin for
input, the corresponding bit in the TRISx
register must also be configured for input
(i.e., set to ‘1’).

11.6.2.2 Output Mapping
In contrast to inputs, the outputs of the peripheral pin
select options are mapped on the basis of the pin. In
this case, a control register associated with a p articular
pin dictates the peripheral output to be mapped. The
RPORx registers are used to control output mapping.
Like the RPINRx registers, each register contains sets
of 5-bit fields, with each set associated with one RPn
pin (see Register 11-15 through Register 11-27). The
value of the bit field corresponds to one of the
peripherals, and that perip heral’s output is mapped to
the pin (see Table 11-2 and Figure 11-3).
The list of peripherals for output mapping also includes
a null value of ‘00000 because of the mapping
technique. This permits any given pin to remain
unconnected from the output of any of the pin
selectable peripherals.

11.6.3 CONTROLLING CONFIGURATION
CHANGES
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. PIC24H devices include three features to
prevent alterations to the peripheral map:
Control register lock sequence
Continuous state monitoring
Configuration bit pin select lock
11.6.3.1 Control Register Lock
Under normal operation, writes to the RPINRx and
RPORx registers are not allowed. Attempted writes
appear to execute normally , but the contents of the reg-
isters remain unchanged. To change these registers,
they must be unlocked in hardware. The register lock is
controlled by the IOLOCK bit (OSCCON<6>). Setting
IOLOCK prevents writes to the control registers;
clearing IOLOCK allows writes.
To set or clear IOLOCK, a specific command sequence
must be executed:
1. Wr ite 0x46 to OSC C ON <7:0>.
2. Wr ite 0x57 to OSC C ON <7:0>.
3. Clear (or set) the IOLOCK bit as a single
operation.
Unlike the similar seq uence with the oscillators LOCK
bit, IOLOCK remains in one state until changed. This
allows all of the peripheral pin selects to be configure d
with a single unlock sequence followed by an update to
all control registers, then locked with a second lock
sequence.
11.6.3.2 Continuous State Monitoring
In addition to being protected from direct writes, the
contents of the RPINRx and RPORx registers are
constantly monitored in hardware by shadow registers.
If an unexpected change in any of the registers occurs
(such as cell disturbances caused by ESD or other
external events), a configuration mismatch Reset is
triggered.
11.6.3.3 Configuration Bit Pin Select Lock
As an additional level of safety, the device can be
configured to prevent more than one write session to
the RPINRx and RPORx registers. The IOL1WAY Con-
figuration bit (FOSC<5>) blocks the IOLOCK bit from
being cleared after it has been set once. If IOLOCK
remains set, the register unlock procedure does not
execute, and the peripheral pin select control registers
cannot be written to. The only way to clear the bit and
re-enable peripheral re mapping is to perform a device
Reset.
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session. Programming
IOL1WAY allows user applications unlimited access
(with the proper use of the unlock sequence) to the
peripheral pin select registers.
Note: MPLAB® C30 provides built-in C
language functions for unlocking the
OSCCON register:
__builtin_write_OSCCONL(value)
__builtin_write_OSCCONH(value)
See MPLAB Help for more information.

11.7 Peripheral Pin Select Registers
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 family of devices
implement 27 registers for remappable peripheral
configuration:
14 Input Remappable Peripheral Reg isters:
- RPINR0-RPINR1, RPINR3-RPINR4,
RPINR7, RPINR10-RPINR11, RPINR18-
RPINR23 and PRINR26
13 Output Remappable Peripheral Registers:
- RPOR0-RPOR12
Note: Input and Output Register values can only
be changed if the IOLOCK bit
(OSCCON<6>) is set to ‘0’. See
Section 11.6.3.1 “Control Register
Lock” for a specific command sequence.

12.0 TIMER1
The Timer1 module is a 16-bit timer, which can serve
as the time counter for the real-time clock, or operate
as a free-running interval timer/counter.
The Timer1 module has the following unique features
over other timers:
Can be operated from the low power 32 kHz
crystal oscillator available on the device
Can be operated in Asynchronous Counter mode
from an external clock source.
The external clock input (T1CK) can optionally be
synchronized to the internal device clock and the
clock synchronization is performed after the
prescaler.
The unique features of Timer1 allow it to be used for
Real Time Clock (RTC) applications. A block diagram
of Timer1 is shown in Figure 12-1.
The T imer1 module can operate in one of the following
modes:
Timer mode
Gated Timer mode
Synchronous Counter mode
Asynchronous Counter mode
In Timer and Gated Timer modes, the input clock is
derived from the internal instructi on cycle clock (FCY).
In Synchronous and Asynchronous Counter modes,
the input clock is derived from the external clock input
at the T1CK pin.
The T imer modes are determined by the following bits:
T imer Clock Source Control bit (TCS): T1CON<1>
Timer Synchronization Control bit (TSYNC):
T1CON<2>
Timer Gate Control bit (TGATE): T1CON<6>
Timer control bit setting for different operating modes
are given in the Table 12-1.

The Timer2/3 and Timer4/5 modules can operate in
one of the following modes:
Timer mode
Gated Timer mode
Synchronous Counter mode
In Timer and Gated Timer modes, the input clock is
derived from the internal instruction cycle clock (FCY).
In Synchronous Counter mode, the input clock is
derived from the external clock input at T xC K pin.
The timer modes are determined by the following bits:
TCS (TxCON<1>): T imer Clock Source Control bit
TGATE (TxCON<6>): Timer Gate Control bit
Timer control bit settings for different operating modes
are given in the Table 13-1.
TABLE 13-1: TIMER MODE SETTINGS
13.1 16-Bit Operation
To configure any of the timers for individual 16-bit
operation:
1. Clear the T32 bit corresponding to that timer.
2. Select the timer prescaler ratio using the
TCKPS<1:0> bits.
3. Set the Clock and Gating modes using the TCS
and TGATE bits.
4. Load the timer period value into the PRx
register.
5. If interrupts are required, set the interrupt enable
bit, TxIE. Use the priority bits, TxIP<2:0>, to set
the interrupt priority.
6. Set the TON bit.
13.2 32-Bit Operation
A 32-bit timer module can be formed by combining a
Type B and a Type C 16-bit timer module. For 32-bit
timer operation, the T32 control bit in the Type B T imer
Control register (TxCON<3>) must be set. The Type C
timer holds the most significant word (msw) and the
Type B timer holds the least significant word (lsw) for
32-bit operation.
When configured for 32-bit operation, only the Type B
Timer Control register (TxCON) bits are required for
setup and control. Type C timer control register bits are
ignored (except TSIDL bit).
For interrupt control, the combined 32-bit timer uses
the interrupt enable, interrupt flag and interrupt priority
control bits of the Type C timer. The interrupt control
and status bits for the Type B timer are ig nored during
32-bit timer operation.
The Type B and T y pe C timers that can be combined to
form a 32-bit time r are listed in Table 13-2.
TABLE 13-2: 32-BIT TIMER
A block diagram representation of the 32-bit timer mod-
ule is shown in Figure 13-3. The 3 2-timer module can
operate in one of the following modes:
Timer mode
Gated Timer mode
Synchronous Counter mode
To configure the features of Timer2/3 or Timer4/5 for
32-bit operation:
1. Set the T32 contro l bi t .
2. Select the prescaler ratio for Timer2 or Timer4
using the TCKPS<1:0> bits.
3. Set the Clock and Gating modes using the
corresponding TCS and TGATE bits.
4. Load the timer period value. PR3 or PR5 con-
tains the most significant word of the value,
while PR2 or PR4 con tains the least significant
word.
5. If interrupts are required, set the interrupt enable
bits, T3IE or T5IE. Use the priority bits,
T3IP<2:0> or T5IP<2:0> to set the interrupt pri-
ority. While Timer2 or Timer4 controls the timer,
the interrupt appears as a Timer3 or Timer5
interrupt.
6. Set the corresponding TON bit.
The timer value at any point is stored in the register
pair, TMR3:TMR2 or TMR5:TMR4, which always
contains the most significant word of the count, while
TMR2 or TMR4 contains the least signifi c ant word.

14.0 INPUT CAPTURE
The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices support up to
four input capture channels.
The input capture modu le captures the 16-bit value of
the selected Time Base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
Simple Capture Event modes:
- Capture timer value on every falling edge of
input at ICx pin
- Captu re timer value on every rising edge of
input at ICx pin
Capture timer value on every edge (rising and
falling)
Prescaler Capture Event modes:
- Captu re timer value on every 4th rising edge
of input at ICx pin
- Captu re timer value on every 16th rising
edge of input at ICx pin
Each input capture channel can select one of two
16-bit timers (Timer2 or Timer3) for the time base.
The selected timer can use either an internal or
external clock.
Other operational features include:
Device wake-up from capture pin during CPU
Sleep and Idle modes
Interrupt on input capture event
4-word FIFO buffer for capture values:
- Interrupt optionally generated after 1, 2, 3 or
4 buffer locations are filled
Use of input capture to provide additional sources
of external interrupts

15.0 OUTPUT COMPARE The Output Compare module can select either Timer2
or Timer3 for its time base. The module compares the
value of the timer with the value of one or two compare
registers depending on the operating mode selected.
The state of the output pin changes when the timer
value matches the compare register value. The Output
Compare module generates either a single output
pulse or a sequence of output pulses, by cha ngin g the
state of the output pin on the compare match events.
The Output Compare module can also generate
interrupts on compare match events.
The Output Compare module has multiple operating
modes:
Active-Low One-Shot mode
Active-Hi g h On e-Shot mode
Toggle mode
Delayed One-Shot mode
Continuous Pulse mode
PWM mode without fault protection
PWM mode with fault protection

16.0 SERIAL PERIPHERAL
INTERFACE (SPI) The Serial Peripheral Interface (SPI) module is a
synchronous serial interface useful for communicating
with other peripheral or microcontroller devices. These
peripheral devices can be serial EEPROMs, shift
registers, display drivers, analog-to-digital converters,
etc. The SPI module is compatible with Motorola® SPI
and SIOP.
Each SPI module consists of a 16-bit shift register,
SPIxSR (where x = 1 or 2), used for shifting data in and
out, and a buffer register, SPIxBUF. A control register,
SPIxCON, configures the module. Additionally, a status
register, SPIxSTAT, indicates status conditions.
The serial interface consists of 4 pins:
SDIx (serial data input)
SDOx (serial data output)
SCKx (shift clock input or output)
SSx (active-low slave select)
In Master mode operation, SCK is a clock output. In
Slave mode, it is a clock input.

17.0 INTER-INTEGRATED
CIRCUIT™ (I2C™)
The Inter-Integrated Circuit (I2C) module provides
complete hardware support for both Slave and
Multi-Master modes of the I2C serial communication
standard, with a 16-bit interface.
The I2C module has a 2-pin in terface:
The SCLx pin is clock.
The SDAx pin is data.
The I2C module offers the following key features:
•I
2C interface supporting both Master and Slave
modes of operation.
•I
2C Slave mode supports 7-bit and 10-bit
addressing
•I
2C Master mode supports 7-bit and 10-bit
addressing
•I
2C port allows bidirectional transfers between
master and slaves
Serial clock synchronization for I2C port can be
used as a handshake mechanism to suspend and
resume serial transfer (SCLREL control)
•I
2C supports multi-master operation, detects bus
collision and arbitrates accordingly
17.1 Operating Modes
The hardware fully implements all the master and slave
functions of the I2C Standard and Fast mode
specifications, as well as 7-bit and 10-bit addressing.
The I2C module can operate either as a slave or a
master on an I2C bus.
The following types of I2C operation are supported:
•I
2C slave operation with 7-bit addressing
•I
2C slave operation with 10-bit addressing
•I
2C master operation with 7-bit or 10-bit addressing
For details about the communication sequence in each
of these modes, refer to the “dsPIC33F/PIC24H Family
Reference Manual”. Please see the Microchip website
(www.microchip.com) for the latest dsPIC33F/PIC24H
Family Reference Manual chapters.
17.2 I2C Registers
I2CxCON and I2CxSTAT are control and status
registers, respectively. The I2CxCON register is
readable and writable. The lower six bits of I2CxSTAT
are read-only. The remaining bits of the I2CSTAT are
read/write:
I2CxRSR is the shift register used for shifting data
internal to the module and the user application
has no access to it
I2CxRCV is the receive buffer and the register to
which data bytes are written, or from which data
bytes are read
I2CxTRN is the transmit register to which bytes
are written during a transmit operation
The I2CxADD register holds the slave address
A status bit, ADD10, indicates 10-bit Address
mode
The I2CxBRG acts as the Baud Rate Generator
(BRG) reload value
In receive operations, I2CxRSR and I2CxRCV together
form a double-buffered receiver. When I2CxRSR
receives a complete byte, it is transferred to I2CxRCV,
and an interrupt pulse is generated.

19.0 ENHANCED CAN (ECAN™)
MODULE
19.1 Overview
The Enhanced Contro ller Area Network (ECAN) module
is a serial interface, useful for communicating with other
CAN modules or microcontroller devi ces. This inte rface/
protocol was designed to allow communications within
noisy environments. The PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices cont ain up to two ECAN modules.
The ECAN module is a communication controller
implementing the CAN 2.0 A/B protocol, as defined in
the BOSCH CAN specification. The module supports
CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B
Active versions of the protocol. The module
implementation is a full CAN system. The CAN specifi-
cation is not covered within this data sheet. The reader
can refer to the BOSCH CAN specification for further
details.
The modul e fe at ures are as fol low s:
Implementation of the CAN protocol, CAN 1.2,
CAN 2.0A and CAN 2.0B
Standard and extended data frames
Data length of 0-8 bytes
Programmable bit rate up to 1 Mbit/sec
Automatic response to remote transmission
requests
Up to eight transmit buffers with application speci-
fied prioritization and abort capability (each buffer
can contain up to 8 bytes of data)
Up to 32 receive buffers (each buffer can contain
up to 8 bytes of data)
Up to 16 full (standard/extended identifier)
acceptance filters
Three full acceptance filter masks
DeviceNet™ addressing support
Programmable wake-up functionality with
integrated low-pass filter
Programmable Loopback mode supports self-test
operation
Signaling via interrupt capabilities for all CAN
receiver and tr an smitter error states
Programmable clock source
Programma bl e link to input capt ure module (IC2
for CAN1) for time-stamping and network
synchronization
Low-power Sleep and Idle mode
The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messa ges a re transmitted
by first loading the appropriate data registers. Status
and errors can be checked by readin g the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then match ed against filters to
see if it should be received and stored in one of the
receive registers.
19.2 Frame Types
The ECAN module transmits various types of frames
which include data messages, or remote transmissi on
requests initiated by the user, as o ther frames that are
automatically generated for control purposes. The
following frame types are supported:
Standard Data Frame:
A standard data frame is generated by a node when
the node wishes to transmit data. It includes an 1 1-bit
S t andard Identifier (SID), but not an 18-bit Extended
Identifier (EID).
Extended Data Frame:
An extended data frame is similar to a standard data
frame, but includes an ex tended identifier as well.
Remote Frame:
It is possible for a destination node to request the
data from the source. For this purpose, the
destination node sends a remote frame with an iden-
tifier that matches the identifi er of the requ ired data
frame. The appropriate data source node sends a
data frame as a response to this remote request.
Error Frame:
An error frame is generated by any node that detects
a bus error. An error frame consists of two fields: an
error flag field and an error delimiter field.
Overload Frame:
An overload frame can be generated by a node as a
result of two conditions. First, the node detects a
dominant bit during interframe space which is an ille-
gal condition. Second, due to internal conditions, the
node is not yet able to start reception of the next
message. A node can generate a maximum of 2
sequential overload frames to delay the start of the
next message.
Interframe Space:
Interframe space separates a proceeding frame (of
whatever type) from a following data or remote
frame.

19.3 Modes of Operation
The ECAN module can operate in one of several
operation modes selected by the user. These modes
include:
Initialization mode
Disable mode
Normal Operation mode
Listen Only mode
Listen All Messages mode
Loopback mode
Modes are requested by setting the REQOP<2:0> bits
(CiCTRL1<10:8>). Entry into a mode is Acknowledged
by monitoring the OPMODE<2:0> bits
(CiCTRL1<7:5>). The module does not change the
mode and the OPMODE bits until a change in mode is
acceptable, generally during bus Idle time, which is
defined as at least 11 consecutive recessive bits.
19.3.1 INITIALIZATION MODE
In the Initialization mode, the module does not transmit
or receive. The error counters are cleared and the inter-
rupt flags remain unchanged. The user application has
access to Configuration registers that are access
restricted in other modes. The module protects the user
from accidentally violating the CAN protocol through
programming errors. All registers which control the
configuration of the module can not be modified while
the module is on-line. The ECAN module is not allowed
to enter the Configuration mode while a transmission is
taking place. The Configuration mode serves as a lock
to protect the following registers:
All Module Control registers
Baud Rate and Interrupt Configuration registers
Bus Timing registers
Identifier Acceptance Filter registers
Identifier Acceptance Mask registers
19.3.2 DISABLE MODE
In Disable mode, the ECAN mod ule does not transmit
or receive. The module can set the WAKIF bit due to
bus activity, however, any pending interrupts remains
and the error counters retains their value.
If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the
module enters the Module Disable mode. If the module is
active, the module waits for 11 recessive bits on the CAN
bus, detect that condition as an Idle bus, then accept the
module disable command. When the OPMODE<2:0>
bits (CiCTRL1<7:5>) = 001, that indicates whether the
module successfully went into Module Disable mode.
The I/O pins reverts to normal I/O function when the
module is in the Module Disable mode.
The module can be programmed to apply a low-pass
filter function to the CiRX input line while the module or
the CPU is in Sleep mode. The WAKFIL bit
(CiCFG2<14>) enables or disables the fi lter.
19.3.3 NORMAL OPERATION MODE
Normal Operation mode is selected when
REQOP<2:0> = 000. In this mode, the module is
activated and the I/O pins assumes the CAN bus
functions. The module transmits and receive CAN bus
messages via the CiTX and CiRX pins.
19.3.4 LISTEN ONLY MODE
If the Listen Only mode is activated, the module on the
CAN bus is passive. The transmitter buffers revert to
the port I/O function. The receive pins remain inputs.
For the receiver , no error flags or Acknowledge signals
are sent. The error counters are deactivated in this
state. The Listen Only mode can be used for detecting
the baud rate on the CAN bus. To use this, it is neces-
sary that there are at least two further nodes that
communicate with each other .
19.3.5 LISTEN ALL MESSAGES MODE
The module can be set to ig nore all errors and receive
any message. The Listen All Messages mode is
activated by setting REQOP<2:0> = 111. In this mode,
the data which is in the message assembly buffer, until
the time an error occurred, is copied in the receive
buffer and can be read via the CPU interface.
19.3.6 LOOPBACK MODE
If the Loopback mode is activated, the module con-
nects the internal transmit signal to the internal receive
signal at the module boundary. The transmit and
receive pins revert to their port I/O function.
Note: T ypically, if the ECAN module is allowed to
transmit in a particular mode of operation
and a transmission is requested immedi-
ately after the ECAN module has been
placed in that mode of operation, the mod-
ule waits for 11 consecutive recessive b its
on the bus before starting transmission. If
the user switches to Disable mode within
this 11-bit period, then this transmission is
aborted and th e correspond ing TXABT bit
is set and TXREQ bit is cleared.

ECAN Message Buffers are part of DMA RAM Memory .
They are not ECAN special function registers. The user
application must directly wr ite into th e DMA RAM area
that is configured for ECAN Message Buffers. The
location and size of the buffer area is defined by the
user application.

20.0 10-BIT/12-BIT
ANALOG-TO-DIGITAL
CONVERTER (ADC1)
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices have up to 13
ADC input channels.
The AD12B bit (AD1CON1<10>) allows each of the
ADC modules to be configured by the user as either a
10-bit, 4-sample/hold ADC (default configuration) or a
12-bit, 1-sample/hold ADC.
20.1 Key Features
The 10-bit ADC configuration has the following key
features:
Successive Approximation (SAR) conversion
Conversion speeds of up to 1.1 Msps
Up to 13 analog input pins
External voltage reference input pins
Simultaneous sampling of up to four analog input
pins
Automatic Channel Scan mode
Selectable conversion trigger source
Selectable Buffer Fill modes
Operation during CPU Sleep and Idle modes
The 12-bit ADC configuration supports all the above
features, except:
In the 12-b i t c on fi guration, conversion speeds of
up to 500 ksps are supported
There is only one sample/hold amplifier in the
12-bit configuration, so simultaneous sampling of
multiple channels is not supported.
Depending on the particular device pinout, the ADC
can have up to 13 analog input pins, designated AN0
through AN12. In addition, there are two analog input
pins for external voltage reference connections. These
voltage reference inputs can be shared with other
analog input pins. The actual number of analog input
pins and external voltage reference input configuration
depends on the specific device.
Block diagrams of the ADC module are shown in
Figure 20-1 and Figure 20-2.
20.2 ADC Initialization
The following configuration steps should be performed.
1. Configure the ADC module:
a) Select port pins as analog inputs
(AD1PCFGH<15:0> or AD1PCFGL<15:0>)
b) Select voltage reference source to match
expected range on analog inputs
(AD1CON2<15:13>)
c) Select the analog conversion clock to
match desired data rate with processor
clock (AD1CON3<7:0>)
d) Determine how many S/H channels are
used (AD1CON2<9:8> and
AD1PCFGH<15:0> or AD1PCFGL<15:0>)
e) Select the appropriate sample/conversion
sequence (AD1CON1<7:5> and
AD1CON3<12:8>)
f) Select how conversion results are
presented in the buffer (AD1CON1<9:8>)
g) Turn on ADC module (AD1CON1<15>)
2. Configure ADC interrupt (if required):
a) Clear the AD1IF bit
b) Select ADC interrupt priority
20.3 ADC and DMA
If more than one conversion result needs to be buffered
before triggering an i nterrupt, DMA data transfers can
be used. ADC1 can trigger a DMA data transfer. If
ADC1 is selected as the DMA IRQ source, a DMA
transfer occurs when the AD1IF bit gets set as a result
of an ADC1 sample conversion sequence.
The SMPI<3:0> bits (AD1CON2<5:2>) are used to
select how often the DMA RAM buffer pointer is
incremented.
The ADDMABM bit (AD1CON1<12>) determines how
the conversion results are filled in the DMA RAM buffer
area being used for ADC. If this bit is set, DMA buffers
are written in the order of conversion. The module
provides an address to the DMA channel that is the
same as the address used for the non-DMA
stand-alone buffer . If the ADDMABM bit is cleared, then
DMA buffers are written in Scatter/Gather mode. The
module provides a scatter/gather addre ss to the DMA
channel, based on the index of the analog input and the
size of the DMA buffer.
Note 1: This data sheet summarizes the features
of the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 families of
devices. It is not intended to be a compre-
hensive reference source. To comple-
ment the information in this data sheet,
refer to Section 16. “Analog-to-Digital
Converter (ADC)” (DS70183) of the
“dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip website (www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Note: The ADC module needs to be disabled
before modifying the AD12B bit.

21.1 Comparator Voltage Reference
21.1.1 CONFIGURING THE COMPARATOR
VOLTAGE REFERENCE
The Voltage Reference module is controlled through
the CVRCON register (Register 21-2). The comparator
voltage reference provides two ranges of output
voltage, each with 16 distinct levels. The range to be
used is selected by the CVRR bit (CVRCON<5>). The
primary difference between the ranges is the size of the
steps selected by the CVREF Selection bits
(CVR3:CVR0), with one range offering finer resolution.
The comparator reference supply voltage can come
from either VDD and VSS, or the external VREF+ and
VREF-. The voltage source is selected by the CVRSS
bit (CVRCON<4>).
The settling time of the comparator voltage reference
must be considered when changing the CVREF
output.

22.0 REAL-TIME CLOCK AND
CALENDAR (RTCC)
This chapter discusses the Real-Time Clock and
Calendar (RTCC) module, available on
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices, and its operation.
The following are some of the key features of this
module:
• Time: hours, minutes and seconds
• 24-hour format (military time)
• Calendar: weekday, date, month and year
• Alarm configurable
• Year range: 2000 to 2099
• Leap year correction
• BCD format for compact firmware
• Optimized for low-power operation
• User calibration with auto-adjust
• Calibration range: ±2.64 seconds error per month
• Requirements: External 32.768 kHz clock crystal
• Alarm pulse or seconds clock output on RTCC pin
The RTCC module is intended for applications where
accurate time must be maintained for extended periods
of time with minimum to no intervention from the CPU.
The RTCC module is optimized for low-power usage to
provide extended battery lifetime while keeping track of
time.
The RTCC module is a 100-year clock and calendar
with automatic leap year detection. The range of the
clock is from 00:00:00 (midnight) on January 1, 2000 to
23:59:59 on December 31, 2099.
The hours are available in 24-hour (military time)
format. The clock provides a granularity of one second
with half-second visibility to the user.

22.1 RTCC Module Registers
The RTCC module registers are organized into three
categories:
RTCC Control Registers
RTCC Value Registers
Alarm Value Registers
22.1.1 REGISTER MAPPING
To limit the register interface, the RTCC Timer and
Alarm Time registers are accessed through
corresponding register pointers. The RTCC Value
register window (RTCVALH and RTCVALL) uses the
RTCPTR bits (RCFGCAL<9:8>) to select the desired
timer register pair (see Table 22-1).
By writing the RTCVALH byte, the RTCC Pointer value,
RTCPTR<1:0> bits, decrement by one until they reach
00’. Once they reach ‘00’, the MINUTES and
SECONDS value will be accessible through RTCVALH
and RTCVALL until the pointer value is manually
changed.
TABLE 22-1: RTCVAL REGISTER MAPPING
The Alarm Value register window (ALRMVALH and
ALRMVALL) uses the ALRMPTR bits
(ALCFGRPT<9:8>) to select the desired Alarm register
pair (see Table 22-2).
By writing the ALRMVALH byte, the Alarm Pointer
value, ALRMPTR<1:0> bits, decrement by one until
they reach ‘00’. Once they reach ‘00’, the ALRMMIN
and ALRMSEC value will be accessible through
ALRMVALH and ALRMVALL until the pointer value is
manually changed.
TABLE 22-2: ALRMVAL REGISTER
MAPPING
Considering that the 16-bit core does not distinguish
between 8-bit and 16-bit read operations, the user must
be aware that when reading either the ALRMVALH or
ALRMVALL bytes will decrement the ALRMPTR<1:0>
value. The same applies to the RTCVALH or RTCVALL
bytes with the RTCPTR<1:0> being decremented.
22.1.2 WRITE LOCK
In order to perform a write to any of the RTCC Timer
registers, the RTCWREN bit (RCFGCAL<13>) must be
set (refer to Example 22-1).

Note: This only applies to read operations and
not write operations.
Note: To avoid accidental writes to the timer , it is
recommended that the RTCWREN bit
(RCFGCAL<13>) is kept clear at any
other time. For the RTCWREN bit to be
set, there is only 1 instruction cycle time
window allowed between the 55h/AA
sequence and the setting of RTCWREN;
therefore, it is recommended that code
follow the procedure in Example 22-1.
MOV #NVMKEY, W1 ;move the address of NVMKEY into W1
MOV #0x55, W2
MOV #0xAA, W3
MOV W2, [W1] ;start 55/AA sequence
MOV W3, [W1]

23.0 PROGRAMMABLE CYCLIC
REDUNDANCY CHECK (CRC)
GENERATOR
The programmable CRC generator offers the following
features:
User-programmable polynomial CRC equation
Interr up t ou tput
Data FIFO
23.1 Overview
The module implements a software configurable CRC
generator. The terms of the polynomial and its length
can be programmed using the CRCXOR bits (X<15:1>)
and the CRCCON bits (PLEN<3:0>), respectively.
EQUATION 23-1: CRC EQUATION
To program this polynomial into the CRC generator,
the CRC register bits should be set as shown in
Table 23-1.
TABLE 23-1: EXA MPLE CRC SETUP
For the value of X<15:1>, the 12th bit and the 5th bit are
set to ‘1’, as required by the CRC equation. The 0th bit
required by the CRC equa tion is always XORed. For a
16-bit polynomial, the 16th bit is also always a ssumed
to be XORed; therefore, the X<15:1> bits do not have
the 0th bit or the 16th bit.
The topology of a standard CRC generator is shown in
Figure 23-2.

23.2 User Interface
23.2.1 DATA INTERFACE
To start serial shifting, a1’ must be written to the
CRCGO bit.
The module incorporates a FIFO that is 8 deep when
PLEN (PLEN<3:0>) > 7, and 16 deep, otherwise. The
data for which the CRC is to be calculated must first be
written into the FIFO. The smallest data element that
can be written into the FIFO is one byte. For example,
if PLEN = 5, th en th e size of the d ata is PLEN + 1 = 6.
The data must be written as follows:
data[5:0] = crc_input[5:0]
data[7:6] = ‘bxx
Once data is written into the CRCWDAT MSb (as
defined by PLEN), the value of VWORD
(VWORD<4:0>) increments by one. The serial shifter
starts shifting data into the CRC engine when
CRCGO = 1 and VWORD > 0. When the MSb is
shifted out, VWORD decrements by one. The serial
shifter continues shifting until the VWORD reaches 0.
Therefore, for a given value of PLEN, it will take
(PLEN + 1) * VWORD number of clock cycles to
complete the CRC calculations.
When VWORD reaches 8 (or 16), the CRCFUL bit wil l
be set. When VWORD reaches 0, the CRCMPT bit will
be set.
To continually feed data into the CRC engine, the
recommended mode of operation is to initially “prime”
the FIFO with a sufficient number of words so no
interrupt is generated before the next word can be
written. Once that is done, start the CRC by setting the
CRCGO bit to ‘1’. From that point onward, the
VWORD<4:0> bits should be polled. If they read less
than 8 or 16, another word can be written into the FIFO.
To empty words already written into a FIFO, the
CRCGO bit must be set to ‘1’ and the CRC shifter
allowed to run until the CRCMPT bit is set.
Also, to get the correct CRC reading, it is necessary to
wait for the CRCMPT bit to go high before reading the
CRCWDAT register.
If a word is written when the CRCFUL bit is set, the
VWORD Pointer will roll over to 0. The hardware will
then behave like the FIFO is empty. However, the
condition to generate an interrupt will not be met;
therefore, no interrupt will be generated (See
Section 23.2.2 “Int errupt Operation”).
At least one instruction cycle must pass after a write to
CRCWDAT before a read of the VWORD bits is done.
23.2.2 INTERRUPT OPERATION
When the VWORD<4:0> bits make a transition fro m a
value of ‘1’ to ‘0’, an interrupt will be generated.
23.3 Operation in Power-Saving Modes
23.3.1 SLEEP MODE
If Sleep mode is entered while the module is operating,
the module will be suspended in its current state until
clock execution resumes.
23.3.2 ID LE MO DE
To continue full module operation in Idle mode, the
CSIDL bit must be cleared prior to entry into the mode.
If CSIDL = 1, the module will behave the same way as
it does in Sleep mode; p ending i nterrupt eve nts will be
passed on, even though the module clocks are not
available.

25.1 Configuration Bits
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices provide nonvola-
tile memory implementation for device configuration
bits. Refer to Section 25. “Device Configuration”
(DS70194), in the “dsPIC33F/PIC24H Family
Reference Manual” for more information on this
implementation.
The Configuration bits can be programmed (read as
0’), or left unprogrammed (read as ‘1’), to select
various device configurations. These bits are mapped
starting at program memory location 0xF80000.
The individual Configuration bit descriptions for the
Configuration registers are shown in Table 25-1.
Note that address 0xF80000 is beyond the user program
memory space. It belongs to the configuration memory
space (0x800000-0xFFFFFF), which can only be
accessed using table reads and table writes.
The Device Configuration register map is shown in
Table 25-1.

25.2 On-Chip Voltage Regulator
All of the PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices power their core digital logic at a nominal 2.5V.
This can create a conflict for designs th at are required
to operate at a higher typical voltage, such as 3.3V. To
simplify system design, all devices in the
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 family incorporate an on-chip
regulator that allows the device to run its core logic from
VDD.
The regulator provides power to the core from the other
VDD pins. When the regulator is enabled, a low-ESR
(less than 5 Ohms) capacitor (such as tantalum or
ceramic) must be connected to the VCAP pin
(Figure 25-1). This helps to maintain the stability of the
regulator. The recommended value for the filter capac-
itor is provided in Table 28-13 located in Section 28.1
“DC Characteristics”.
On a POR, it t akes approximately 20 μs for the on-chip
voltage regulator to generate an output voltage. During
this time, designated as TSTARTUP, code execution is
disabled. TSTARTUP is applied every time the device
resumes operation after any power-down.
FIGURE 25-1: CONNECTIONS FOR THE
ON-CHIP VOLTAGE
REGULATOR(1,2,3)
25.3 Brown-out Reset (BOR)
The Brown-out Reset (BOR) module is based on an
internal voltage reference circuit that monitors the
regulated supply voltage VCAP. The main purpose of
the BOR module is to generate a device Reset when a
brown-out condition occurs. Brown-out conditions are
generally caused by glitches on the AC mains (for
example, missing portions of the AC cycle waveform
due to bad power transmission lines, or voltage sags
due to excessive current draw when a large inductive
load is turned on).
A BOR generates a Reset pulse, which resets the
device. The BOR selects the clock source, based on
the device Configuration bit values (FNOSC< 2:0> and
POSCMD<1:0>).
If an oscillator mode is selected, the BOR activates the
Oscillator Start-up Timer (OST). The system clock is
held until OST expires. If the PLL is u sed, the clock is
held until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the PWRT time-out (TPWRT) is applied
before the internal Reset is released. If TPWRT = 0 and
a crystal oscillator is being used, then a nominal delay
of TFSCM = 100 is applied. The total delay in this case
is TFSCM.
The BOR S tatus bit (RCON<1>) is set to indicate that a
BOR has occurred. The BOR circuit continues to oper-
ate while in Sleep or Idle modes and rese ts the device
should VDD fall below the BOR threshold voltage.
Note: It is important for the low-ESR capacitor to
be placed as close as possible to the VCAP
pin.
Note 1: These are typical operating voltages. Refer to
Table 28-13, located in Section 28.1 “DC
Characteristics” for the full operating ranges
of VDD and VCAP.
2: It is important for the low-ESR capacitor to be
placed as close as possible to the VCAP pin.
3: Ty pi ca l V CAP pin voltage = 2.5V when VDD
VDDMIN.

25.4 Watchdog Timer (WDT)
For PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices, the WDT is
driven by the LPRC oscillator. When the WDT is
enabled, the clock source is also enabled.
25.4.1 PRESCALER/POSTSCALER
The nominal WDT cl ock source from LPRC is 32 kHz.
This feeds a prescaler that can be configured for either
5-bit (divide-by-32) or 7-bit (divide-by-128) operation.
The prescaler is set by the WDTPRE Configuration bit.
With a 32 kHz input, the prescaler yields a nominal
WDT time-out period (TWDT) of 1 ms in 5-bit mode, or
4 ms in 7-bit mode.
A variable postscaler divides down the WDT prescaler
output and allows for a wide range of time-out periods.
The postscaler is controlled by the WDTPOST<3:0>
Configuration bits (FWDT<3:0>), which allow the
selection of 16 settings, from 1:1 to 1:32,768. Using the
prescaler and postscaler, time-out periods ranging from
1 ms to 131 seconds can be achieved.
The WDT, prescaler and postscaler are reset:
On any device Reset
On the completion of a clock switch, whether
invoked by software (i.e., setting the OSWEN bit
after changing the NOSC bits) or by hardware
(i.e., Fail-Safe Clock Monitor)
When a PWRSAV instruction is executed
(i.e., Sleep or Idle mode is entered)
When the device exits Sleep or Idle mode to
resume normal operation
•By a CLRWDT instruction during normal execution
25.4.2 SLEEP AND IDLE MODES
If the WDT is enabled, it conti nues to ru n during Slee p or
Idle modes. When the WDT time-out occurs, the device
wakes the device and code execution continues from
where the PWRSAV instruction was executed. The corre-
sponding SLEEP o r IDLE bits (RCON<3,2>) n eeds to be
cleared in software after the device wakes up.
25.4.3 ENABLING WDT
The WDT is enabled or disabled by the FWDTEN
Configuration bit in the FWDT Configuration register.
When the FWDTEN Configuration bit is set, the WDT is
always enabled.
The WDT can be optionally controlled in software
when the FWDTEN Configuration bit has been
programmed to ‘0’. The WDT is enabled in software
by setting the SWDTEN control bit (RCON<5>). The
SWDTEN control bit is cleared on any device Reset.
The software WDT option allows the user application
to enable the WDT for critical code segments and
disable the WDT during non-critical segments for
maximum power savings.
The WDT flag bit, WDTO (RCON<4>), is not automatically
cleared following a WDT time-out. To detect subsequent
WDT events, the flag must be cleared in software.
FIGURE 25-2: WDT BLOCK DIAGRAM
Note: The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.
Note: If the WINDIS bit (FWDT<6>) is cleared,
the CLRWDT instruction should be executed
by the application software only during the
last 1/4 of the WDT period. This CLRWDT
window can be determined by using a timer .
If a CLRWDT instruction is executed before
this window, a WDT Reset occurs.

25.5 JTAG Interface
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices implement a
JTAG interface, which supports boundary scan device
testing, as well as in-circuit programming. Detailed
information on this interface is provided in future
revisions of the document.
25.6 In-Circuit Serial Programming
The PIC24HJ32GP302/304, PIC24HJ64GPX02/X04
and PIC24HJ128GPX02/X04 devices can be serially
programmed while in the end application circuit. This is
done with two lin es for clock and data and three other
lines for power, ground and the programming
sequence. Serial programming allows customers to
manufacture boards with unprogrammed devices and
then program the microcontroller just before shipping
the product. Serial programming also allows the most
recent firmware or a custom firmware to be
programmed. Refer to the “dsPIC33F/PIC24H Flash
Programming Specification” (DS70152) for details
about In-Circuit Serial Programming (ICSP).
Any of the three pairs of programming clock/data pins
can be used:
PGEC1 and PGED1
PGEC2 and PGED2
PGEC3 and PGED3
25.7 In-Circuit Debugger
When MPLAB® ICD 2 is selected as a debugger, the
in-circuit debugging functionality is enabled. This
function allows simple debugging functions when used
with MPLAB IDE. Debugging functionali ty is co ntrolled
through the PGECx (Emulation/Debug Clock) and
PGEDx (Emulation/Debug Data) pin fu nctions.
Any of the three pairs of debugging clock/data pins can
be used:
PGEC1 and PGED1
PGEC2 and PGED2
PGEC3 and PGED3
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, VDD, VSS, and the PGECx/PGEDx pin pair. In
addition, when the feature is enabled, some of the
resources are not available for general use. These
resources include the first 80 bytes of data RAM and
two I/O pins.
25.8 Code Protection and
CodeGuard™ Security
The PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices offer advanced
implementation of CodeGuard Security that supports
BS, SS and GS while, the PIC24HJ32GP302/304
devices offer the intermediate level of CodeGuard
Security that supports only BS and GS. CodeGuard
Security enables multiple parties to securely share
resources (memory, interrupts and peripherals) on a
single chip. This feature helps protect individual
Intellectual Property in collaborative system designs.
When coupled with software encryption libraries,
CodeGuard Security can be used to securely update
Flash even when multiple IPs reside on the single chip.
The code protection features vary depending on the
actual PIC24H implemented. The following sections
provide an overview of these features.
Secure segment and RAM protection is implemented
on the PIC24HJ64GPX02/X04 and
PIC24HJ128GPX02/X04 devices. The
PIC24HJ32GP302/304 devices do not support se cure
segment and RAM protection.
Note: Refer to Section 24. “Programming and
Diagnostics” (DS70246) of the
“dsPIC33F/PIC24H Family Reference
Manual” for further informatio n on usage,
configuration and operation of the JTAG
interface.
Note: Refer to Section 23. “CodeGuard™
Security” (DS70239) of the
“dsPIC33F/PIC24H Family Reference
Manual” for further info rmation on usage,
configuration and operation of
CodeGuard Security.

26.0 INSTRUCTION SET SUMMARY
The PIC24H instruction set is identical to the PIC24F,
and is a subset of the dsPIC30F/33F instruction set.
Most instructions are a single program memory word
(24 bits). Only three instructions require two program
memory locations.
Each single-word instruction is a 24-bit word, divided
into an 8-bit opcode, which specifies the instruction
type and one or more operands, which further specify
the operation of the instruction.
The instruction set is highly ortho gonal an d is gr ouped
into five basic categories:
Word or byte-oriented operations
Bit-oriented operations
Literal operations
Control operations
Table 26-1 shows the general symbols used in
describing the instructions.
The PIC24H instruction set summary in Table 26-2 lists
all the instructio ns, along with the status flags affected
by each instruction.
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
The first source operand whic h is typically a
register ‘Wb’ without any address modifier
The second source operand which is typically a
register ‘Ws’ with or without an address modifier
The destination of the result which is typically a
register ‘Wd’ with or without an address modifier
However , word or byte-oriented file register instructions
have two operands:
The file register specified by the value ‘f’
The destination, which could either be the file
register ‘f’ or the W0 register , which is denoted as
‘WREG’
Most bit-oriented instructions (including simple
rotate/shift instructions) have two operands:
The W register (with or without an address
modifier) or file register (specified by the value of
‘Ws’ or ‘f’)
The bit in the W register or file register
(specified by a literal value or indirectly by the
contents of register ‘Wb’)
The literal instructions that involve data movement may
use some of the following operands:
A literal value to be loaded into a W register or file
register (specified by the value of ‘k’)
The W register or file register where the literal
value is to be loaded (specified by ‘Wb’ or ‘f’)
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
The first source operand which is a register ‘Wb’
without any address modifier
The second source operand which is a literal
value
The destination of the result (only if not the same
as the first source operand) which is typically a
register ‘Wd’ with or without an address mo difier
The control instructions may use some of the following
operands:
A program memory address
The mode of the table read and table write
instructions
All instructions are a single word, except for certain
double word instructions, which were made double
word instructions so that all the required information is
available in these 48 bits. In the second word, the
8 MSbs are ‘ 0’s. If this second word is executed as an
instruction (by itself), it will execute as a NOP.
Most single-word instructions are executed in a single
instruction cycle, unless a conditional test is true, or the
program counter is changed as a result of the
instruction. In these cases, the execution takes two
instruction cycles with the additional instruction cycle(s)
executed as a NOP. Notable exceptions are the BRA
(unconditional/computed branch), indirect CALL/GOTO,
all table reads and writes and RETURN/RETFIE
instructions, which are single-word instructions but take
two or three cycles. Certain instructions that involve skip-
ping over the subsequent instruction require either two
or three cycles if the skip is performed, depending on
whether the instruction being skippe d is a single-word or
double word instruction. Moreover, double word moves
require two cycles. The double word instructions
execute in two instructio n cycl es.

29.0 HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS
This section provides an overview of PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
electrical characteristics for devices operating in an ambie nt temperature range of -40°C to +150°C.
The specifications between -40°C to +150°C are identical to those shown in Section 28.0 “Electrical Characteristics”
for operation between -40°C to +125°C, with the exception of the parameters listed in this section.
Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in
Section 28.0 “Electrical Characteristics is the Industrial and Extended temperature equivalent of HDC10.
Absolute maximum rati ngs for the PIC24HJ32GP302/304, PIC24H J64GPX02/X04 and PIC24HJ128GPX02/X04 high
temperature devices are listed below. Exposure to these maximum rating conditions for extended periods can affect
device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in
the operation listings of this specification is not implied.
Absolute Maximum Ratings(1)

Note 1: Stresses above those listed under “Absolute Maximum Ratings” can cause permanent damage to the
device. This is a stress rating only, and functional operation of the device at those or any other conditions
above those indicated in the operation listings o f this specification i s not implied. Exposure to maximum
rating conditions for extended periods can affect device reliability.
2: Maximum allowable current is a function of devi c e maximum power dissipation (see Table 29-2).
3: Unlike devices at 125°C a nd below, the specifications in this section also apply to the CLKOUT, VREF+,
VREF-, SCLx, SDAx, PGCx and PGDx pins.
4: AEC-Q100 reliability testing for devices intended to operate at 150°C is 1,000 hours. Any design in which
the total operating time from 125°C to 150°C will be greater than 1,000 hours is not warranted without prior
written approval from Microchip Technology Inc.
5: Refer to the Pin Diagrams section for 5V tolerant pins.
