// how to use this WDT with the LPC1114

//Watchdog wdt;    This sets the WDT up per code above - call it just before main();
 
//int main() {      
    
//wdt.kick(XX);     // set XX to LONGER than the main processing loop worst case
// LOOP             // this is the main program loop
//  .
//  .
//  .
//  wdt.kick(); // reset the WDT here
// GOTO: LOOP
//}
