3.2 Clock Settings

3.2.1 Overview of clock settings

The main system and subsystem clocks to be used during debugging can be selected from (1) to (3) below.

(1) Clock that is already mounted on emulation board

(2) Clock that is mounted by user

(3) External clock

If the target system includes an internal clock, select either (1) Clock that is already mounted on emulation

board or (2) Clock that is mounted by user. For an internal clock, a resonator is connected to the target device and

the target device’s internal oscillation circuit is used. An example of the external circuit is shown in part (a) of Figure

3-2. During emulation, the resonator that is mounted on the target system is not used. Instead, the clock that is

mounted on the emulation board connected to the IE-78K0-NS or IE-78K0-NS-A is used.

If the target system includes an external clock, select (3) External clock.

For an external clock, a clock signal is supplied from outside the target device and the target device’s internal

oscillation circuit is not used. An example of the external circuit is shown in part (b) of Figure 3-2.

Caution The IE system will be hung-up if the main system clock is not supplied normally. Moreover, be

sure to input a rectangular wave as the clock from the target. The IE system does not operate if

the crystal resonator is connected to X1 (main system clock) and XT1 (subsystem clock).

(2) Clock that is mounted by user

The user is able to mount any clock supported by the set specifications on the IE-780078-NS-EM1.

(a) For main system clock

Remove the crystal oscillator (X1) that is already mounted on the emulation board, and mount either the

parts board on which the resonator to be used is mounted or an oscillator. This method is useful when using

a different frequency from that of the pre-mounted clock.

(1) When using clock that is already mounted on emulation board

When the IE-780078-NS-EM1 is shipped, an 8.38 MHz crystal oscillator is already mounted in the IE-780078-NS-

EM1’s X1 socket. When using the factory-set mode settings, there is no need to make any other hardware

settings.

When starting the integrated debugger (ID78K0-NS), open the configuration dialog box and select “Internal” in the

area (Clock) for selecting the CPU’s clock source (this selects the emulator’s internal clock).

CHAPTER 4 DIFFERENCES BETWEEN TARGET DEVICES AND TARGET INTERFACE CIRCUITS

This chapter describes differences between the target device’s signal lines and the signal lines of the IE-780078-

NS-EM1’s target interface circuit.

Although the target device is a CMOS circuit, the IE-780078-NS-EM1’s target interface circuit consists of emulation

circuits such as an emulation CPU, TTL, and CMOS-IC.

When the IE system is connected with the target system for debugging, the IE system performs emulation so as to

operate as the actual target device would operate in the target system.

However, some minor differences exist since the operations are performed via the IE system’s emulation.

(1) Signals input or output from the emulation CPU and

PD780009

(2) Signals input or output from the emulation CPU and

PD78F0078

(3) Other signals

The IE-780078-NS-EM1’s circuit is used as follows for signals listed in (1) to (3) above.

(1) Signals input or output from the emulation CPU and

PD780009

See Figure 4-1 Equivalent Circuit of Emulation Circuit (1).

• P47 to P40

• P57 to P50

• P67 to P64

(2) Signals input or output from the emulation CPU and

PD78F0078

See Figure 4-2 Equivalent Circuit of Emulation Circuit (2).

• P03 to P00

• P25 to P20

• P36 to P30

• P75 to P70

• P17 to P10

• AVREF, AVSS

CHAPTER 5 CAUTIONS ON USE

Observe the following when using the IE-780078-NS-EM1.

(1) In the external diffusion mode, the read data in address xx24H of the external memory becomes undefined.

Measures: Use IE-78K0-NS control code L or later, or IE-78K0-NS-A control code E or later. When using

products with control codes earlier than the above, set the PM4 register to 00H (port 4 set to

output mode).

(2) The value of the interrupt request flag register IF1L (FFE2H) after reset is 04H.

Measures: After reset, set the IF1L register to 00H.
