  11          // Description   : Demonstrates a use of a timer interval counter to
  12          //              wake the ADuC842 out of Power down mode after a user
  13          //              specified Power down time.
  14          //
  15          //              The LED will, on power up, flash at 5Hz. After 5s
  16          //              the ADuC842 will enter power down mode (the LED will 
  17          //              stop flashing in the off position). 
  18          //              
  19          //              By pressing the external interrupt 0 button (INT0) or
  20          //              when the user specified time runs out (20s in this 
  21          //              example) the ADuC842 will wake up and continue 
  22          //              blinking as before for 5s before entering power down
  23          //              mode again.
