Notes on the Watchdog Function:
Notes on Debugging in CPU Rewrite Mode:
Note on Software Breaks:
When using the watchdog function of the MCU, check the box of “Debug the program using the watchdog
timer” in the MCU tab of the Init dialog box. If this check box is selected, while the user program remains idle
the emulator is performing refresh processing (by writing to the watchdog timer start register) within the
emulator control program. If this check box is unselected, the emulator may run out of control after the user
program has stopped.
When not using the watchdog function of the MCU, do not select the box of “Debug the program using the
watchdog timer”. If this check box is selected, while the user program remains idle the emulator is performing
refresh processing (by writing to the watchdog timer start register) within the emulator control program, and the
watchdog timer starts. If the user program is reexecuted, the watchdog timer underflows generating a watchdog
timer interrupt or a reset.
If the reset circuit of the user system has a watchdog timer, disable it when using the emulator.
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 you do not debug a program in CPU rewrite mode, uncheck the box.
When you debug a program in CPU rewrite mode, the block 0 area (FFF000h--FFFFFFh) must not be rewritten.
Otherwise, the emulator will be out of control.
When debugging in CPU rewrite mode is enabled, you cannot use the following functions.
Do not use the following functions to the rewrite control program area (from setting CPU rewrite mode select
bit to releasing it). If any of these are used, malfunctions may occur (e.g. The emulator cannot shift to CPU
rewrite mode or contents of ROM cannot be read our properly.).
A software break generates a break interruption by forcibly inserting a BRK instruction “08h” instead of an
instruction code. Therefore, when referencing the result of a trace in bus mode, “08h” is displayed for the
instruction fetch address where a software break is set.
