Appendix A. Watch-Dog Timer 

The Watch-Dog Timer is provided to ensure that standalone 
systems can always recover from catastrophic conditions that 
caused the CPU to crash. This condition may be occurred by 
external EMI or a software bug. When the CPU stops working 
correctly, hardware on the board will either perform a hardware 
reset (cold boot) or a non-maskable interrupt (NMI) to bring the 
system back to a known state. 
 
The Watch-Dog Timer is controlled by two I/O ports.

Timer. 

043/843 

(hex) 

Read 

Disable the Watch-Dog Timer. 

 
To enable the Watch-Dog Timer, a read from I/O port 443H 
must be performed. This will enable and activate the countdown 
timer which will eventually time out and either reset the CPU or 
cause an NMI depending on the setting of JP11. To ensure this 
reset condition does not occur, the Watch-Dog Timer must be 
periodically refreshed by reading the same I/O port 443H. This 
must be done within the time out period that is selected by 
jumper group JP10. 
 
A tolerance of at least 30% must be maintained to avoid 
unknown routines within the operating system (DOS), such as 
disk I/O that can be very time consuming. Therefore if the time 
out period has been set to 10 seconds, the I/O port 443H must 
be read within 7 seconds. 
 

Note: When exiting a program, it is necessary to disable the 

Watch-Dog Timer, otherwise the system will reset.
