+
+        GETSUPPORT returns the watchdog_info struct, and
+        GETSTATUS returns the supported options. GETBOOTSTATUS
+        returns a 1 if the last reset was caused by the
+        watchdog and a 0 otherwise. This watchdog can not be
+        disabled once it has been started. The wdt_period kernel
+        parameter selects which bit of the time base changing
+        from 0->1 will trigger the watchdog exception. Changing
+        the timeout from the ioctl calls will change the
+        wdt_period as defined above. Finally if you would like to
+        replace the default Watchdog Handler you can implement the
+        WatchdogHandler() function in your own code.
