       description "
           The watchdog device allows applications to make use of a
           timer facility. First the application should register an
           action routine with the watchdog device, and start the
           watchdog running. After this the application must call a
           watchdog reset function at regular intervals, or else the
           device will cause the installed action routine to be
           invoked. The assumption is that the watchdog timer should
           never trigger unless there has been a serious fault in
           either the hardware or the software, and the application's
           action routine should perform an appropriate reset
           operation."
