How to normally perform a debugging system of R8C UART monitor program?

Latest Updated:05/11/2011

Question:

Why can’t debugging of a user program, in which the watchdog timer is used, be performed normally in a debugging system of the R8C UART monitor program?

Answer:

When using the R8C/10 to R8C/17 Groups, since the watchdog timer is not refreshed while the monitor program operates, a watchdog timer interrupt is generated and normal debugging cannot be performed. Do not use the watchdog timer in the user program when using the debugging system.
When using MCUs other than the R8C/10 to R8C/17 Groups, the watchdog timer is refreshed while the monitor program operates. When the user program is executed in which the watchdog timer is used, if the monitor program is executed due to referring or changing the memory contents, note that the watchdog timer is refreshed.
