I am facing difficulty using watchdog timer for lpc2214.I feed the watchdog(0xaa,0x55) once every scan cycle, which is around 20ms.I have five interrupts enabled;but the wd resets controller periodically . watchdog timeout is around 2sec. Are there any special precations to be taken to avoid interrupts during watchdog feeding sequence.
more... The time between feeding the puppy is the time spent in main() plus the time taken to execute each and every invocation of each and every ISR while main() get from a feeding to the next. Erik
