Notes on Debugging in CPU Rewrite Mode:
T
o 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 E
2
dataFlash:
When you are debugging the E
2
dataFlash, do not stop the user program during operating the
E
2
dataFlash. Otherwise, as the operation to the E
2
dataFlash 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
E
2
dataFlash will occur during execution of the user program.
