Watchdog Timer Programming Procedure
To program the watchdog timer, you must execute a program that writes a value to I/
O port address 443/444 (hex) for Enable/Disable. This output value represents time
interval. The value range is from 01 (hex) to FF (hex), and the related time interval is
1 to 255 seconds.
After data entry, your program must refresh the watchdog timer by rewriting the I/O
port 443 and 443 (hex) while simultaneously setting it. When you want to disable the
watchdog timer, your program should read I/O port 444 (hex).
