        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."
