Jaya: the LPC allows you to choose between reset and interrupt when Watchdog is triggered by means of the WDMOD register. If you set WDMOD to 0x01, you'll get a normal IRQ through the VIC when the watchdog is triggered; if you set it to 0x03, you will get a reset (which is similar to a hardware reset).
