Watchdog Timer 

This section describes how to use the Watchdog Timer, including disabled, enabled, 

and trigger functions. 

The system is equipped with a programmable time-out period watchdog timer.  
You can use your own program to enable the watchdog timer.  Once you have 

enabled the watchdog timer, the program should trigger the I/O every time before 

the timer times out.  If your program fails to trigger or disable this timer before it 
times out, e.g. because of a system hang-up, it will generate a reset signal to reset 

the system.  The time-out period can be programmed to be set from 1 to 255 

seconds or minutes.
