Sample of Watchdog application
Assume that program A must be kept running for a specified period of time:
1. Initialize the Watchdog Timer with a countdown time value bigger than the running time of
program A.
2. If program A has no problems when its running time has passed, it will disable or reset the
Watchdog Timer before its countdown time has reached zero.
3. If program A is running and experiencing any problem that causes the system to stop
working, the Watchdog Timer will automatically reboot the system when countdown time
has reached zero.
Refer to the below flowchart of editing program A.
