21. Notes on On-Chip Debugger
When using on-chip debugger to develop and debug programs for the R8C/1A Group and R8C/1B Group, take note of
the following.
(1) Do not access the related UART1 registers.
(2) Some of the user flash memory and RAM areas are used by the on-ship debugger. These areas cannot be
accessed by the user.
Refer to the on-chip debugger manual for which areas are used.
(3) Do not set the address match interrupt (registers AIER, RMAD0, and RMAD1 and fixed vector tables) in a
user system.
(4) Do not use the BRK instruction in a user system.
Connecting and using the on-chip debugger has some special restrictions. Refer to the on-chip debugger manual for
on-chip debugger details.
