Therefore, use an open-collector output buffer or a CR reset circuit as the reset circuit for the user system. The recommended pull-up value is 4.7 k or more. The MCU can be reset by outputting "L" from the E8a emulator. However, if the reset IC output is "H", the user system reset circuit cannot be set to "L". As such, the E8a emulator will not operate normally.

Notes on Using the E8a Emulator (5) Stack area used by the E8a emulator The E8a emulator uses up to 32 bytes of the stack pointer (ISP) during a user program break. Therefore, set aside 32 bytes for the stack area. (6) Reset The reset vector is used by the E8a emulator program. If the MCU is reset (hardware reset) while executing the user program, control is transferred to the E8a emulator program and the user program is forced to stop. Do not use the software reset and watchdog timer reset, otherwise the E8a emulator will run out of control. If the automatic memory update is enabled in the memory or watch window, do not perform a hardware reset to the MCU. Otherwise the E8a emulator will run out of control. (7) Interrupts used by the E8a emulator program (unusable) The BRK2 instruction interrupt and single-step interrupt are used by the E8a emulator program. Therefore, make sure the user program does not use any of these interrupts. The E8a emulator changes these interrupt vector values to the values to be used by the emulator. No problems occur if the interrupt vector values are written in the user program. (8) Interrupts used by the E8a emulator program (NMI) If NMI interrupts are used, be sure to take the necessary precautions before executing the user program like disabling the automatic update in the watch window or fix the display in the memory window before running the program so that memory accesses do not occur during an execution. If an NMI interrupt occurs while the user program halts or when memory contents are referenced or modified during user program execution, the E8a emulator cannot control the MCU. (9) DMACII transfer complete interrupt If DMACII transfer complete interrupts are used, be sure to take the necessary precautions before executing the user program like disabling the automatic update in the watch window or fix the display in the memory window before running the program so that memory accesses do not occur during an execution. If a DMACII transfer complete interrupt occurs while the user program halts or when memory contents are referenced or modified during user program execution, the E8a emulator cannot control the MCU. (10) Reserved area The addresses not specified in the Hardware Manual of MCUs are reserved area. Do not change the contents. Otherwise, the E8a emulator cannot control the MCU.

Notes on Using the E8a Emulator 6.2 Flash memory 6.2.1 Note on debugging in CPU rewrite mode (1) Unrewritable area in CPU rewrite mode When debugging in CPU rewrite mode, do not rewrite CPU for the following area. If these areas are rewritten, the E8a emulator will not control the MCU. - Block 0 area (addresses FFFF8000h - FFFFFFFFh) and block containing the E8a emulator program (2) Operation in CPU rewrite mode - Do not halt the user program while setting up the CPU rewrite mode and releasing it. If halted, the E8a emulator may not control the MCU. - Disable the automatic update in the watch window or fix the display in the memory window before running the program so memory accesses do not occur during an execution. - To check the data after executing the CPU rewrite mode, halt the program after releasing the CPU rewrite mode and refer to the memory window, etc. - When rewriting the Flash memory in the program area, select Menu -> [Setup] -> [Emulator] -> [System...] to open the [Configuration] dialog box in the High-performance Embedded Workshop. In this dialog box, change the [Flash memory synchronization] setting to [Flash memory to PC] and set the debugger cache to OFF. In this setting, the Flash memory is read whenever a break occurs, which takes some time. Use it with the [Disable] setting except when debugging in CPU rewrite mode. 6.2.2 Note on rewriting flash memory (1) Do not reset nor execute debugging operations to the MCU when rewriting the flash memory. Flash memory rewrite ends when the "Flash memory write end" is displayed in the output window of the Highperformance Embedded Workshop. If the MCU is reset or debugged when rewriting the flash memory, the user program or the E8a emulator program may be disrupted. Flash memory rewrite occurs: - When downloading the user program - After setting PC breaks in the flash memory and executing the user program - After canceling PC breaks in the flash memory and executing the user program - After rewriting the value of the flash memory in the memory window and executing the user program 6.2.3 Note on flash memory during user program execution Do not rewrite the flash area from the memory window, etc., except from the user program during user program execution. 6.2.4 MCUs used for debugging When debugging, the Flash memory is frequently rewritten by the E8a emulator. Therefore, do not use an MCU that has been used for debugging in products. Also, as the E8a emulator program is written to the MCU while debugging, do not save the contents of the MCU Flash memory which were used for debugging nor use them as the ROM data for products.

Notes on Using the E8a Emulator 6.3 Count source protect mode When downloading the program that enables the count source protect mode, the E8a emulator sets both of the bit 2 and bit 3 of the optional function select area (OFS: FFFFFFEFh) to 0b. b3, b2: Watchdog Timer Prescaler Select Bit 0 0 : Divide-by-8 (WDK3 to WDK2 = 00b) Applicable MCUs: R32C/120, R32C/121, R32C/151, R32C/152, R32C/153, R32C/156, R32C/157, R32C/160 and R32C/161 6.4 Power supply (1) Consumption current When the E8a emulator does not supply power to the user system, it consumes the power voltage of the user system from several mA to more than 10 mA. This is because the user power supply drives 74LVC125, 74LVC1T45 and 74LVC2T45 to make the communication signal level match the user system power supply voltage. (2) E8a emulator power supply When writing a program with the E8a emulator for mass production processes, the program requires reliability, so do not use the E8a emulator power supply function. Supply power separately to the user system according to the allowable voltage for MCU writing. Voltage supplied from the E8a emulator depends on the quality of the USB power supply of the PC, and as such, precision is not guaranteed. Note that when debugging the system which operates the MCU with a dual power supply, power cannot be supplied from the E8a. 6.5 Operation during a user program halt (1) Peripheral I/Os during a halt During a user program halt, interrupts are not accepted although peripheral I/Os continue to run. For example, a timer interrupt is not accepted although the timer continues to count when a user program is stopped by a break after the timer started. REJ10J1877-0201 Page 38 of 43 Rev.2.01 Jun. 26, 2009 E8a Emulator 6. Notes on Using the E8a Emulator 6.6 Debug functions (1) Memory access during user program execution When referring to or modifying the memory contents, the user program is temporarily halted. For this reason, a real-time emulation cannot be performed. When a real-time emulation is necessary during a program execution, disable the automatic update in the watch window or fix the display in the memory window before running the program so that memory accesses do not occur during an execution. (2) Setting of address match break during user program execution When adding or cancelling the address match break, the user program is temporarily halted. For this reason, a real-time emulation cannot be performed. (3) PC break point When downloading a user program after modifying it, the set address of PC break may not be corrected normally depending on the modification. Therefore, break points other than the set PC breaks may shift. After downloading a user program, check the setting of PC breaks in the event point window and reset it. If a low-speed clock such as the sub clock is used as the operation clock of the MCU, setting or canceling PC breaks may take time. Use event breaks as the first choice. (4) "Go to cursor" function The "Go to cursor" function is actualized using an address match break. Therefore, when you execute the "Go to cursor" command, all the address match breaks and hardware breaks you set become invalid, while all the PC breaks remain valid. (5) Debugging in stop mode or wait mode When debugging in stop mode or wait mode, do not operate windows until the program stops at the breakpoint by setting the breakpoint at the line of the program which will be executed after the stop mode or wait mode is cancelled. In addition, disable the automatic update in the watch window or fix the display in the memory window before running the program so memory accesses do not occur during an execution. When the program is forcibly stopped or when the memory is referred to or modified in stop mode or wait mode, these mode will be cancelled. (6) Low power consumption mode When debugging in low power consumption mode, do not operate windows until the program stops at the breakpoint by setting the breakpoint at the line of the program which will be executed after the low power consumption mod is cancelled. (7) Debugging the E2PROM emulation data flash area This software does not support the following function. - Reference and setting of E2PROM emulation data flash area by emulator commands REJ10J1877-0201 Page 39 of 43 Rev.2.01 Jun. 26, 2009 E8a Emulator 6. Notes on Using the E8a Emulator (8) DMAC and DMACII during a user program halt When the user program is halted or when the memory is referred to or modified during user program execution, DMA transfer is disabled. In such cases, the E8a emulator sets the registers below as following. Therefore, if you refer to the registers below in the memory window, etc., it shows that DMA is disabled. - DMA0 Mode Register (DMD0) Transfer mode select bit (bit 1, 0) - DMA1 Mode Register (DMD1) Transfer mode select bit (bit 1, 0) - DMA2 Mode Register (DMD2) Transfer mode select bit (bit 1, 0) - DMA3 Mode Register (DMD3) Transfer mode select bit (bit 1, 0) - Interrupt Control Register Interrupt request level select bit (bit 2, 1, 0) - Interrupt Control Register Interrupt request bit (bit 3) 00: DMA transfer disabled 00: DMA transfer disabled 00: DMA transfer disabled 00: DMA transfer disabled 000: Level 0 (interrupt disabled) 0: Interrupt not requested [*1] Do not enable DMA transfer from the memory window, etc., but enable it in the user program. Note [*1] When restarting the user program, though the E8a emulator sets back the value of a DMA mode register to the previous value that was set before the program stops, the interrupt request bit remains 0. REJ10J1877-0201 Page 40 of 43 Rev.2.01 Jun. 26, 2009 E8a Emulator 6. Notes on Using the E8a Emulator (9) Exceptional step execution a) Software interrupt instruction Step execution cannot be performed in the internal processing of instructions (undefined, overflow, BRK and INT) which generate a software interrupt continuously in the program (see Figure 6.2). NOP NOP INT#3 NOP JMP MAIN INT_3: NOP NOP NOP REIT Program should be stopped at this address. Passes through if the STEP execution is carried out. Figure 6.2 Example of Software Interrupt Instruction b) INT instruction To debug the user program with the INT instruction, set a PC break for the internal processing of the INT instruction and execute the program with the GO command (see Figure 6.3). NOP INT #3 NOP JMP MAIN INT_3: NOP Break NOP REIT Execute using GO command. Figure 6.3 Example of INT Instruction (10) Note on using automatic memory update When the automatic memory update is enabled in the memory or watch window, do not execute Step Out or Multiple-step. Otherwise, it will take longer to update memory data and the operation will be delayed. (11) I/O file I/O files for the working sample MCUs are not prepared. Refer to "I/O File Format" in the online help of the Highperformance Embedded Workshop to make an I/O file for those MCUs.
