        The watchdog IO device allows applications to make use of a

        timer facility. Depending on the underlying hardware device

        driver, a watchdog timeout will either cause a board reset

        or an action routine to be called. The application must call

        the watchdog reset function at regular intervals, or else the

        device will timeout. The assumption is that the watchdog timer

        should never trigger unless there has been a serious fault in

        either the hardware or the software."
