/********************************************************* 
 This sketch demonstrates the use of a watchdog timer.
 The watchdog timer causes a processor reset to occur if
 it is allowed to time out. When the sketch is running
 inside the second while loop, the watch dog timer is
 consistently reset to prevent a timeout. When PB0 is 
 pulled high, it breaks out of the while loop and causes 
 the watch dog timer to reset the processor.
