Description : What is watchdog timer ? Explain the implementation of time out for ATM with block diagram and program.
Answer : A special type of timer is a watchdog timer, which will reset the system after a predefined timeout. Watchdog timer reset timer every X time unit, else timer generates a signal ... be loaded into timereg. This is to prevent erroneous software from unintentionally resetting the watchdog timer.
