The timeout signal is used to initiate corrective actions. If, due to a hardware fault or program error, the computer fails to restart the watchdog, the timer will elapse and generate a timeout signal. Watchdog timers are widely used in computers to facilitate automatic correction of temporary hardware faults, and to prevent errant or malevolent software from disrupting system operation.ĭuring normal operation, the computer regularly restarts the watchdog timer to prevent it from elapsing, or "timing out".
