23. Notes on Emulator Debugger
When using the emulator debugger to develop the R8C/20 and R8C/21 Groups program and debug, pay the following
attention.
Connecting and using the emulator debugger has some peculiar restrictions. Refer to each emulator debugger manual
for emulator debugger details.
(1)
Do not use the following flash memory areas because these areas are used for the emulator debugger.
When debugging of these areas, intensive evaluation on the real chip is required.
