Hello Could some tell me how to properly set the prescaler for the watchdog timer. I have been using pics for a while now but have never used the watchdog timer. Don't ask why! I am using a 15C56A. Also, will the prescaler be set back to zero when the CLRWDT command is used or when the chip is reset after a watchdog time out?
