B: Programming the Watchdog Timer

The OPEN (660) system features a watchdog timer which can generate a system reset if the CPU processing comes to a halt. This feature ensures the system dependability during unattended operation. The watchdog timer is programmable. In order to program the watchdog timer, a program writing I/O port address 443 (hex) needs to be written first. The output data is a value of time interval. The value ranges from 01(hex) to 3F(hex), and the related time interval ranges from 0 to 30 seconds.

Data

00

0 sec.

01

2 sec.

02

4 sec.

03

6 sec.

0F

30 sec.

After entering the data, the program has to refresh the watchdog timer by rewriting the I/O port 443 (hex) and setting it at the same time. To disable the watchdog timer, the program should read I/O port 143 (hex).
