Setup 2.6 Connecting the E30A Emulator and the User System 2.6.1 Using the Coaxial Connector (1) Processing NSD pin Pull up NSD pin of the target MCU to Vcc1 with a 4.7k resistor. (It cannot be connected directly to Vcc1 and Vcc2.) Furthermore, be sure that the wiring from NSD pin to the connector is shortest possible. (2) Mounting part in place Mount the coaxial connector included with the product (HRM-300-126B(40) made by Hirose Electric) on designated position of the user system. (3) Connection procedure Plug the 50 coaxial cable (gray) included with the product into the E30A emulator and the coaxial connector on the user system. Although the cable can be connected over a distance, the power supply condition of the user system cannot be monitored. Furthermore, since only a software reset is possible from the E30A emulator, a hardware reset is required when the emulator debugger is started or when a communication error occurs. Figure 2.4 is a connection diagram showing how to connect the E30A emulator and user system using the coaxial connector. Figure 2.4 Connection diagram when using the coaxial connector CAUTION Caution for Insertion/Removal of the Coaxial Cable: When inserting or removing the coaxial cable, be aware not to rotate it. The center core of the coaxial cable may be broken. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 25 of 66 E30A Emulator User's Manual 2. Setup 2.6.2 Using the Coaxial Converter Board R0E00030ACKZ00 (1) Processing NSD pin Pull up NSD pin of the target MCU to Vcc1 with a 4.7k resistor. (It cannot be connected directly to Vcc1 and Vcc2.) Furthermore, be sure that the wiring from NSD pin to the connector is shortest possible. (2) Mounting part in place Mount the 2.54mm pitch 3-pin socket included with the product (PIC-FS03-G+R made by Honda Tsushin Kogyo) on designated position of the user system. (3) Connection procedure Plug the 50 coaxial cable included with the product (gray) into the E30A emulator and CN1 on coaxial converter board. Fit CN2 on coaxial converter board into the 3-pin socket on user system. It can be turned 180 degrees as it is fitted into place. Although the cable can be easily removed/inserted and can be connected over a distance, the power supply condition of the user system cannot be monitored. Furthermore, since only a software reset is possible from the E30A emulator, a hardware reset is required when the emulator debugger is started or when a communication error occurs. Figure 2.5 is a connection diagram showing how to connect the E30A emulator and user system using the coaxial converter board. Figure 2.5 Connection diagram when using the coaxial converter board R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 26 of 66 E30A Emulator User's Manual 2. Setup 2.6.3 Using the Option Board R0E00030ACKZ10 (1) Processing NSD pin Pull up NSD pin of the target MCU to Vcc1 with a 4.7k resistor. (It cannot be connected directly to Vcc1 and Vcc2.) Furthermore, be sure that the wiring from NSD pin to the connector (pin 4) is shortest possible. (2) Mounting part in place Mount the 2.54mm pitch 8-pin socket included with the product (PIC-FS08-G+R made by Honda Tsushin Kogyo) on designated position of the user system. Furthermore, mount the 2.54mm pitch 8-pin straight pin included with the product (PIC-MSA08-2G made by Honda Tsushin Kogyo) on CN4 (solder side) of the option board. (3) Wiring of Vcc1 and Vcc2 Vcc1 (pin 1) is used to monitor the power supply condition of the user system and as power supply for the RST# and RSTMSK output buffers. Vcc2 (pin 2) monitors the power supply condition of the user system. (4) Wiring of RST# and RSTMSK Since the target MCU is reset in hardware from the E30A emulator, connect RST# signal (pin 6) to the RESET# terminal of the target MCU. If the reset circuit of the user system uses an open-drain output, pull it up to Vcc1 with a 4.7k-22k resistor. The same applies for the power-on reset case making use of a CR circuit. If the reset signal is generated as CMOS output from other logic devices, the user system may have a RSTMSK signal connected to disable the output. Since RSTMSK input is indeterminate when the E30A emulator is not connected, it requires a pulldown resistor. (5) Connection procedure Plug the 10-pin flat cable included with the product into CN3 on the option board. Plug the 50 coaxial cable (gray) included with the product into CN1 on the coaxial converter board. Fit CN2 on the coaxial converter board into CN2 on the option board. It can be turned 180 degrees as it is fitted into place. Fit CN4 on the option board into the 8-pin socket on the user system. Alternatively, the coaxial converter board can be attached to pins 3-5 of the 8-pin socket on the user system without using the option board. (6) Compatibility with the E30 emulator (old product) If you have hitherto been using the 8-pin flat cable of the E30 emulator, you can attach the 2.54mm pitch 8-pin right angle connector included with the product (FFC-8LAMEP1B made by Honda Tsushin Kogyo) to CN4 (component side) of the option board, for connection to the user system. However, since the non-coaxial NSD wiring becomes longer, it is recommended that the connector on the user system be replaced with the 8-pin socket, and that the 8-pin straight pin be used for connection.

Select this check box when you want to debug a program in CPU rewrite mode. In this mode, software breaks in the internal ROM area of the MCU cannot be used. Note on Debugging in CPU Rewrite Mode: Do not stop the user program during debugging in CPU rewrite mode. Otherwise, the emulator will be out of control. Furthermore, before executing a user program, be sure to disable automatic updating of the windows to ensure that no memory accesses will occur during execution of the user program. To inspect data after CPU rewrite operation, stop the program after exiting CPU rewrite mode and inspect the data in the memory window or another appropriate window. (4) Use ECC for E2 Data Flash Select this check box when you want to use ECC for E2 Data Flash. (5) Work Area For Monitor Program Specify the start address of the internal RAM area of the MCU to be used by the debug monitor program. Approximately 1.2 KB of the internal RAM will be used as needed, for example, to download a user program. Since the memory contents are saved before debugging starts, you do not need to be specifically concerned, except that the following cannot be specified. - Areas overlapping the interrupt stack Areas which overlap with the interrupt stack to be used in the user program cannot be specified. Also, the address 0400h cannot be specified since it is used as a temporary stack by the emulator after reset is released. In the case of the 63 KB internal RAM (0400h-FFFFh), 0500h/0600h ... FA00h/FB00h can be specified. In the case of the 32 KB internal RAM (0400h-83FFh), 0500h/0600h ... 7E00h/7F00h can be specified. - Areas to or from which DMA-transferred R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 34 of 66 E30A Emulator User's Manual 3. Starting Up the Emulator Debugger 3.2.2 Debugging Information Tab This tab permits you to select a compiler, select an object format, and choose to specify On Demand for debug information. (1) Compiler Select the compiler you are using. (2) Object Format Select the format of the object file that is output by the compiler you are using. (3) On Demand Select this check box when you want to hold debug information in a temporary file in order to reduce the amount of memory used by the host machine. (4) Display the instruction format specifier in disassembly Specify whether or not to show the instruction format specifier in disassemble display. (5) Always treat variables of enumerator type with unknown size as 1 byte If the debug information contains information on an enumerator type that does not have size information, it is possible to specify whether to handle it always as being 1 byte in size. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 35 of 66 E30A Emulator User's Manual 3. Starting Up the Emulator Debugger 3.2.3 Emulator Tab This tab permits you to specify the clock supplied to the target MCU and data acquisition interval of the RAM monitor. (1) Clock Specify the XIN clock and the frequency that supplied to the target MCU. - Xin: Enter the frequency of the XIN clock, and select Generated (Internal generator circuit) or Internal (Oscillator circuit board). - PLL: Enter the frequency of the MCU's internal PLL, which should be the same as the value to be set in the user program. - CCR: Enter the value for the MCU's internal clock control register, which should be the same as the value to be set in the user program. Notes on Clock Setting: The emulator sets the PLL-related settings before starting up in order to secure a communication path. In a user program, be sure to set the same value of the PLL-related settings specified by the emulator debugger. Otherwise, the emulator will be out of control. The divide ratios of the CPU clock and peripheral clock can be changed in the user program. The XIN clock is used to enter the debug mode and to stop the user program forcibly. Therefore, do not stop the XIN clock in the user program. The PLL clock divided by the base clock divider is used for communication between the emulator and the MCU. Therefore, do not change the PLL frequency and the divide ratio of the base clock in the user program. When the emulator is connected, the PLL clock stop bits are ignored. Therefore, the PLL keeps oscillating even when the WAIT or STOP instruction is executed. This means that BCLK is also oscillating, so that control returns from WAIT or STOP by an INT8, 7 or 6 or other interrupt request. The clock can be switched to a low speed clock (f256, fC, fOCO4). However, as the CPU operation clock becomes slower, the response speed of the emulator debugger becomes also slower. Furthermore, the internal flash ROM cannot be rewritten during a low speed clock operation. Therefore, do not use software breaks. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 36 of 66 E30A Emulator User's Manual 3. Starting Up the Emulator Debugger (2) Data acquisition interval in MCU running state (1 - 100) ms Specify the data acquisition interval (byte or word data). At this interval the functions such as the RAM monitor acquire the memory data while the user program is running. 1 - 100 ms can be specified. Note on Data Acquisition during MCU Execution: Using a function that acquires the memory data during user program execution, such as RAM monitor function, results in the realtime capability becoming impaired because the debug monitor program intervenes. Also, in order to complete processing of the debug monitor program as fast as possible, do not operate the MCU's internal DMA during the processing. (3) Do not communicate with MCU while target is executing. Specify whether or not to communicate with the MCU when executing a user program. While the user program is running, the emulator communicates with the MCU, for example, to check the operating status of the MCU, or to receive the trace information from the MCU. The PLL clock divided by the base clock divider is used for communication between the emulator and the MCU. Therefore, when executing the STOP or WAIT instruction, or when temporarily switching to the PLL self-oscillation mode, select this check box to avoid communication breakdown. The debug function cannot be used because the emulator does not communicate with the MCU when executing the user program. However, it is possible to press the stop button after restored to the base clock specified in the Clock column. 3.2.4 Script Tab This tab permits you to specify a script file. (1) Init File If you have any script that is automatically executed at startup, specify that file. - Click the "Refer..." button to open the Select Script File dialog box. - Select the desired script file.

This mode is used when using the E30A emulator as the flash ROM writer. Select a load module file to be downloaded. - Click "Add..." to open a dialog box to select a load module file. Multiple files can be selected. - To cancel the selection, select the file and click "Remove...". If you want to enable the verification and checksum functions, select the check box. You cannot debug the program in writer mode. Restart or terminate the emulator debugger after writing the program. Notes on Writing the ID code: The ID code is written into the flash memory only when the program was downloaded in writer mode. When operating in other than the writer mode, no ID code is written into the flash memory even when the program is downloaded. In that case, an ID code consisting entirely of FFh is assumed. 3.3 Resetting the User System When using the coaxial connector or the coaxial converter board for connecting the E30A emulator and user system, by clicking "OK" in the Init dialog box, the dialog box shown below will be displayed. When using the option board, the dialog is not displayed because the target MCU is reset in hardware from the emulator. - If the user system has already been powered on, reset the user system. If the power for the user system is turned off, turn the power on. - Click "OK". Notes on Power Supply to the User System: The emulator does not supply power to the user system. Provide power to the user system separately. Do not change the voltage of the user system after turning on the power.

Starting Up the Emulator Debugger 3.5 Setting the Emulator Debugger Operating Environment When a communication path between the E30A Emulator and target MCU is established, the Emem dialog box shown below is displayed. Set each tab described below and click "OK". 3.5.1 Internal Flash Memory Overwrite Tab This tab permits you to specify whether or not to overwrite each block of the internal flash ROM in the MCU. (1) Flash ROM Block If you want to keep the data when you download a user program or data table, check the blocks of contents you want to keep intact. The address list is expressed in units of internal flash ROM blocks of the MCU. The selected blocks, those flagged by a check mark, require extra time because their contents need to be read out before being programmed. Therefore, we recommend leaving blocks unselected. - When you select the check box for any block, the content of that block is read out into the host machine and the data to be downloaded is written over it inside the PC before the block is erased and programmed. - When you deselect the check box for any block, the data to be downloaded is written to the block after being erased. - Click the Select All button, and all blocks will be selected. - Click the Clear All button, and all blocks will be deselected. (2) E2 Data Flash is not erased on download If you want to keep the data in the E2 data flash when you download a user program or data table, select this check box. - When you select the check box, the data in the E2 data flash is read out into the host machine and the data to be downloaded is written over it inside the PC before the block is erased and programmed. - When you deselect the check box, the data to be downloaded is written to the block after being erased. - When E2 data flash is not embedded in the MCU, this setting is invalid.

This dialog box allows you to specify whether or not individual sectors (blocks) of external flash memory should be overwritten. - Settings per sector of the selected external flash memory are automatically displayed in the list. - When the checkbox in the Overwrite column is checked, the selected sector is overwritten (merged) when the program is downloaded. - To change per-sector settings, enter the start and end addresses in the Address edit box and click the Set button. If the sector thus changed has had its "Overwrite" option checked, it is overwritten without erasure when the program is downloaded. If the sector has "Disable download" checked, it is neither erased nor downloaded at download time. - If "Write after all sectors are erased." is selected, all sectors will be erased when the user program is downloaded.

Debugging Functions 4.1 Break Function 4.1.1 Software Break If the breakpoint you set is a software breakpoint, the program stops before executing the instruction at the set breakpoint - Up to 256 break points can be set. - You can specify breakpoints in the internal RAM of the MCU, the internal flash ROM of the MCU, and the RAM on the user system. - If breakpoints in the internal flash ROM of the MCU are specified, the need arises for instruction rewrite/writeback processing in block units. 4.1.2 Execution Address Break This is a kind of event break by the internal debug circuit of the MCU. It specifically is a pre-execution break that causes execution of the user program to stop at a specified address. - Up to 8 break points can be set (used for hardware breaks, trace points, and time measurement events in common). - Since there is no need for instruction rewrite/writeback processing, the response speed is fast. 4.1.3 Hardware Break This is a kind of event break by the internal debug circuit of the MCU. It specifically is a post-execution break that causes execution of the user program to stop upon detecting data access at a specified address. - Up to 8 break points can be set (used for execution address breaks, trace points, and time measurement events in common). - You can set a specified address range (using 2 events). - You can set three conditions, e.g., read, write, and read/write. - Only one instance of data comparison break can be specified (event E5 only). Several bytes from the beginning of the MCU's internal RAM (8 bytes at the addresses 0400h -- 0407h) are used for data comparison by the debug monitor program. These bytes cannot be used in the user program when using a data comparison break. Notes on Execution Address Break and Hardware Break: Do not set breaks in the area designated below. This restriction is due to specifications of the MCU's internal debug circuit. 0100 0000h - FEFF FFFFh Note on Data Comparison Break: For data comparison break, the debug monitor program compares the data after the debug interrupt occurs at the specified address to determine whether or not to cause a break. Using this function results in the realtime capability becoming impaired because the debug monitor program intervenes. Also, in order to complete processing of the debug monitor program as fast as possible, do not operate the MCU's internal DMA during the processing. In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz and CPU 64MHz, for example, it takes 6s to return to the user program after the data comparison results in a mismatch. 4.1.4 Break Combination Event breaks by the internal debug circuit of the MCU can be cascaded to constitute a state transition break at up to 8 points in the forward direction. If all of the events are used for a state transition break, program execution will break when the events E7, E6, ..., and E0 all have occurred in that order. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 45 of 66 E30A Emulator User's Manual 4. Debugging Functions 4.2 Trace Function 4.2.1 Trace Capacity The following can be selected depending on the trace mode chosen in the event setting window. - Trace priority 8M events can be traced. The trace information is output from the MCU and recorded to the emulator trace memory. The user program execution may be delayed depending on the event occurrence interval because the MCU processes the trace information output prior to others. - MCU execution priority 512 events can be traced. The trace information is recorded to the trace RAM of the MCU's internal debug circuit. Therefore, this mode does not affect the execution speed of the user program. Note on Affect on User Program in Trace Priority Mode: In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz and CPU 64MHz, for example, it takes 5s to output trace information for each event. If the average of event occurrence interval among 512 events is less than 5s, the CPU operation will be suspended, because the trace information is output via the trace RAM of the MCU's internal debug circuit. 4.2.2 Trace Contents You can select information on branch sources and destinations, information on conditional branches, information on data accesses, or mixed information of branch sources and destinations, and data accesses. - - Information on branch sources and destinations Branch source address and branch destination address are recorded as an event. Conditional branch information Branch information (success/failure of conditional branches) are recorded in a compressed format. Up to 48 of conditional branches are recorded as an event, so that the communication amount of the trace information can be reduced and the affect on execution speed of the user program can be reduced even in trace priority mode. To record conditional branch information, cancel all trace event settings in the event setting window. An unused event can be used as a break event. Data access information Address, data, data size and read/write information are recorded as an event. Note on Jump in Queue: R32C/100 series has a function that branches to the instructions fetched into the prefetch queue, to improve the processing performance, but the branch source and destination information is not output. Notes on the Data Access Trace: 16-bit word data starting from an odd address and 32-bit long word data assigned differently from the 4byte alignment cannot be traced properly. Data access event by DMA is not the subject of detection. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 46 of 66 E30A Emulator User's Manual 4. Debugging Functions 4.2.3 Extraction Trace An extraction trace with the start event E0 and the end event E4 specified is possible. The events E1 -- E3 or E5 -- E7 that occurred during an interval between E0 to E4 are recorded in the trace RAM. Note on Execution Address Trace Event: When specifying the execution address as the trace event, the results may be different from what you expect because the event is encountered at the prefetch address. Note on Trace Event: Do not set events in the area designated below. This restriction is due to specifications of the MCU's internal debug circuit. 0100 0000h - FEFF FFFFh 4.3 Time Measument Function 4.3.1 Execution Time Measurement You can measure a program execution time between Go and Stop. The 32-bit CPU clock counter allows you to measure a program execution time of up to 67.1 s when operating at 64MHz. 4.3.2 Section Time Measurement You can measure a program execution time between data accesses by trace information. Data access trace information (address, data, data size and read/write) is compared/detected as the measurement start event and measurement end event inside the emulator. The 40-bit asynchronous clock counter inside the emulator enables the section time measurement of more than 24 hours. As a condition of section time measurement, you can specify that the measurement be taken of a time from when the start event occurs till when the end event occurs or a cycle time with which individual events occur. Notes on Time Measurement Function: The execution time and the section time cannot be measured simultaneously. Select either an execution time measurement or a section time measurement. In a section time measurement performed, the data access trace information output from the MCU is compared in the emulator to detect the start and end events. If a large number of data access times is specified, trace output will take a lot of time, leading to errors in section time measurement or affecting execution speed of the user program. In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz, for example, it takes 5s to output the data access trace information for each event. If a data access of less than 5s occurs, a trace output time-dependent error will occur. Furthermore, if such a short data access occurs frequently, execution speed of the user program will be delayed. We recommend write-only settings with least possible events. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 47 of 66 E30A Emulator User's Manual 4. Debugging Functions 4.4 RAM Monitor Function You can view memory data during user program execution by a pseudo-RAM monitor function which is realized by the software using event E5. Data is acquired in byte/word unit by the interval specified in "Data acquisition interval in MCU running state" in the Emulator tab of the Init dialog box. Notes on RAM Monitor Function: The RAM monitor function results in the realtime capability becoming impaired because the debug monitor program intervenes. Also, in order to complete processing of the debug monitor program as fast as possible, do not operate the MCU's internal DMA during the processing. For the RAM monitor function, the emulator generates a debug interrupt and the debug monitor program sends the data to return control to the user program. In the case of XIN 8MHz, PLL 128MHz (16 times), BASE 64MHz and CPU 64MHz, for example, it takes 6s from the debug interrupt occurred to return to the user program. The RAM monitor function should be adjusted for sampling intervals (byte/word data acquisition intervals in ms units) during user program execution. Since the updating time is extended if a wide area is displayed in bytes, we recommend displaying only the necessary area in word size.

When debugging the MCU using this product, be careful about the following precautions. Notes on Clock Setting: The emulator sets the PLL-related settings before starting up in order to secure a communication path. In a user program, be sure to set the same value of the PLL-related settings specified by the emulator debugger. Otherwise, the emulator will be out of control. The divide ratios of the CPU clock and peripheral clock can be changed in the user program. The XIN clock is used to enter the debug mode and to stop the user program forcibly. Therefore, do not stop the XIN clock in the user program. The PLL clock divided by the base clock divider is used for communication between the emulator and the MCU. Therefore, do not change the PLL frequency and the divide ratio of the base clock in the user program. When the emulator is connected, the PLL clock stop bits are ignored. Therefore, the PLL keeps oscillating even when the WAIT or STOP instruction is executed. This means that BCLK is also oscillating, so that control returns from WAIT or STOP by an INT8, 7 or 6 or other interrupt request. The clock can be switched to a low speed clock (f256, fC, fOCO4). However, as the CPU operation clock becomes slower, the response speed of the emulator debugger becomes also slower. Furthermore, the internal flash ROM cannot be rewritten during a low speed clock operation. Therefore, do not use software breaks. Notes on Interrupt Stack: The E30A Emulator uses an interrupt stack of up to 52 bytes. Make sure sufficient space is reserved for the interrupt stack area, with the maximum stack size used by a user program added. If the reserved interrupt stack area is exceeded, the user program may go wild or the emulator may be out of control. The E30A Emulator sets the interrupt stack pointer (ISP) at the beginning address of RAM + 0100h after being reset, and uses that location as a stack area at deassertion of reset. Note on Interrupts That Cannot be Used by the User Program: The BRK2 interrupt, single-step interrupt, and DBC interrupt are used by the emulator program. Therefore, make sure the user program does not use these interrupts. Note on Interrupt Request: Even if a user program is not being executed (including when run-time debugging is being performed), the peripheral I/O such as a timer keeps running. The interrupt request cannot be accepted, because the emulator disables interrupts. The interrupt request is accepted immediately after the user program execution is started. Note on Low Voltage Detection Interrupt: With this product, as the power voltage cannot be changed after powering on the user system, the low voltage detection interrupt cannot be used. Notes on Using the Watchdog Timer: A user program can be debugged by using the MCU's internal watchdog timer if so desired. When the watchdog timer is active, the debug monitor program refreshes it as necessary. Watchdog timers connected external to the MCU cannot be used. Make sure those watchdog timers are disabled while the emulator is in use. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 54 of 66 E30A Emulator User's Manual Appendix B Differences between the Actual MCU and Emulator Note on the Lock Bits for the MCU Internal Flash ROM: The lock bits for the blocks whose contents have been altered by downloading a user program or setting software breakpoints are in an unlocked state. Note on Protect Bit 2 (PRC2): Protect bit 2 (PRC2) behaves in such a way that when the bit is set to 1 to remove write protect and then a write to any address is executed, the bit is write protected again. Note that the bit cannot be cleared by a software operation while single-stepping a program or manipulating the memory window. Note on RDY# Input: Be sure to input "L" to pin RDY# of the user system during the user program executing (when the RUN status LED is lit). Inputting "L" to pin RDY# during the user program stopping may cause a malfunction of the emulator. Note on HOLD# Input: Be sure to input "L" to pin HOLD# of the user system during the user program executing (when the RUN status LED is lit). Inputting "L" to pin HOLD# during the user program stopping may cause a malfunction of the emulator. Note on the MCU Used in Debugging: During debugging, the MCU's internal flash ROM is frequently rewritten as a user program is downloaded or software breakpoints are set or cleared. Do not use any MCU in product once it was used in debugging. Note on Final Evaluation: Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 55 of 66 E30A Emulator User's Manual Appendix C Appendix C Notes on Using This Product Notes on Using This Product Notes on using this product are listed below. When debugging the MCU using this product, be careful about the following precautions. Notes on the Resources of the MCU Used by the Emulator: When you are using a data comparison break (event E5 only), the E30A Emulator uses several bytes from the beginning of the MCU's internal RAM (8 bytes at the addresses 0400h -- 0407h) for data comparison by the debug monitor program. These bytes cannot be used in the user program when using a data comparison break. The E30A Emulator uses approximately 1.2 Kbyte of the internal RAM as needed, for example, to download a user program. Since the memory contents are saved in advance, you do not need to be specifically concerned, except that you cannot specify any area that overlaps the interrupt stack and an area on which DMA operates. Notes on Power Supply to the User System: The emulator does not supply power to the user system. Provide power to the user system separately. Do not change the voltage of the user system after turning on the power. Note on Downloading Firmware: Do not shut off the power while downloading the firmware. If this happens, the product will not start up properly. If the power is shut off unexpectedly, startup the emulator in maintenance mode and redownload the firmware. Note on Quitting the Emulator Debugger: To restart the emulator debugger, always shut power to the emulator and user system off once and then on again. Note on Event Settings: Events are used for breaks, trace, and time measurement in common. For breakpoint settings in the source window, events are given priority in order to reduce the number of times the flash ROM is rewritten. Note that the unused events are used in order of followings. (Extraction start event E0, end of range event E4, and data comparison event E5 are assigned lower priorities.) E7 -> E6 -> E3 -> E2 -> E1 -> E5 -> E4 -> E0 Notes on the Software Breaks: Software breaks execute the tool-only BRK2 command instead of instruction code to generate a BRK interrupt. Be aware that when trace results are referred to in bus display, you will see "BFh" displayed for instruction fetches performed at the addresses that have software breakpoints set. If a user program is altered before being downloaded, the software breakpoints that have been set may be displaced depending on the content of alteration. After downloading a user program, be sure to check the contents of software breakpoints set. Notes on the Data Access Trace: 16-bit word data starting from an odd address and 32-bit long word data assigned differently from the 4byte alignment cannot be traced properly. Data access event by DMA is not the subject of detection. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 56 of 66 E30A Emulator User's Manual Appendix C Notes on Using This Product Notes on Debug Monitor Program Intervention: The following functions result in the realtime capability becoming impaired because the debug monitor program intervenes. Also, in order to complete processing of the debug monitor program as fast as possible, do not operate the MCU's internal DMA during the processing. - Run-time debugging (Referring and modifying the memory during user program execution) - RAM monitor - Data comparison break (when a break for data access is set in event E5) The RAM monitor function should be adjusted for sampling intervals (byte/word data acquisition intervals in ms units) during user program execution. Since the updating time is extended if a wide area is displayed in bytes, we recommend displaying only the necessary area in word size. Note on Trace Mode: When selecting Trace priority, the user program execution may be delayed depending on the event occurrence interval because the MCU processes the trace information output prior to others. When selecting MCU execution priority, the execution speed of the user program is not affected. Notes on the Simultaneous Use of Multiple Functions: Data comparison breaks and RAM monitor cannot be used at the same time. If event E5 is set for a data access break, the RAM monitor functions cannot be specified. If the RAM monitor function needs to be used, event E5 cannot be specified for a data access break. Be aware that if a run-time debug, RAM monitor, or data comparison break is used during a branch trace in which branch addresses are recorded, the recorded information will include branch information (debug monitor program processing address) which the user program does not generate. Note on Debugging in the Stop Mode or Wait Mode: While the user program is running, the emulator communicates with the MCU, for example, to check the operating status of the MCU, or to receive the trace information from the MCU. The PLL clock divided by the base clock divider is used for communication between the emulator and the MCU. Therefore, when executing the STOP or WAIT instruction, or when temporarily switching to the PLL self-oscillation mode, select the check box "Do not communicate with MCU while target is executing" to avoid communication breakdown. The debug function cannot be used because the emulator does not communicate with the MCU when executing the user program. However, it is possible to press the stop button after restored to the base clock specified in the Clock column. When the emulator is connected, the PLL clock stop bits are ignored. Therefore, the PLL keeps oscillating even when the WAIT or STOP instruction is executed. This means that BCLK is also oscillating, so that control returns from WAIT or STOP by an INT8, 7 or 6 or other interrupt request. Note on MCU Reset: Software reset and hardware reset cannot be used during the user program execution. If the MCU is reset during the user program execution, the emulator recovers communication with the MCU and the user program stops in a reset state. R20UT0422EJ0500 Rev.5.00 Dec 01, 2010 Page 57 of 66 E30A Emulator User's Manual Appendix C Notes on Using This Product Notes on Debugging in CPU Rewrite Mode: To debug a program in CPU rewrite mode, check the box "Debug the program using the CPU Rewrite Mode" in the MCU tab of the Init dialog box. When the debugging in CPU rewrite mode is enabled, software breakpoint to the internal ROM area cannot be used. Do not stop the user program during debugging in CPU rewrite mode. Otherwise, the emulator will be out of control. Furthermore, before executing a user program, be sure to disable automatic updating of the windows to ensure that no memory accesses will occur during execution of the user program. To inspect data after CPU rewrite operation, stop the program after exiting CPU rewrite mode and inspect the data in the memory window or another appropriate window. Note on Debugging of E2dataFlash: When you are debugging the E2dataFlash, do not stop the user program during operating the E2dataFlash. Otherwise, as the operation to the E2dataFlash will be suspended, it may not be processed properly even though the user program is restarted. Furthermore, before executing the user program, be sure to disable automatic updating of the windows to ensure that no accesses to the E2dataFlash will occur during execution of the user program.
