/*
  WATCHDOG.C
   demo program for I-7188 to test if I-7188 is reset by watchdog timer.
   If system is reset by watchdog timer,then load this file and run it,
   the program will show the message "System was Reset by watchdog timer."
   Then you can press any key to bypass Watchdog timer test,or wait 5 seconds
   to test watchdog timer.
