Why can't I perform debugging using the watchdog timer function?

Latest Updated:01/16/2009

Question:

I cannot perform debugging normally when using the watchdog timer function in the debug system by the R8C UART Monitor Program. Why is this?

Answer:

For R8C/10-R8C/17 Groups, there is no watchdog timer refresh on the monitor of this debug system, and because of this a watchdog timer interrupt is generated and normal debugging cannot be carried out. Please do not use a watchdog timer in this system.
If you use other than R8C/10-R8C/17 Groups, there is watchdog timer refresh while the monitor is runnning. Please note that the watchdog timer is refreshed when the monitor is intervened by the operations such as a reference or change of the memory contents while the user program using a watchdog timer is running.
