Watchdog timer application note is as following.



Before clearing watchdog timer, check I/O status and check RAM contents can improve system error.



Don‟t clear watchdog timer in interrupt vector and interrupt service routine. That can improve main routine fail.



Clearing watchdog timer program is only at one part of the program. This way is the best structure to enhance the
watchdog timer function.



Example: An operation of watchdog timer is as following. To clear the watchdog timer counter in the top
of the main routine of the program.

Main:

…

; Check I/O.

…

; Check RAM

Err:

JMP $

; I/O or RAM error. Program jump here and

don‟t

; clear watchdog. Wait watchdog timer overflow to reset IC.

Correct:

; I/O and RAM are correct. Clear watchdog timer and

; execute program.

MOV

A, #5AH

; Clear the watchdog timer.

B0MOV
