Watchdog Timer

19. 

WATCHDOG TIMER

The watchdog timer is integrated in the chipset of the MOPS/386A and can issue a reset to

the system or generate a nonmaskable interrupt (NMI). The watchdog timer circuit has to
be triggered within a specified time by the application software. If the watchdog is not

triggered because proper software execution fails or a hardware malfunction occurs, it will
reset the system or generate the NMI.

19.1 

Configuration

You can set the watchdog timer to disabled, reset or NMI mode. You can specify the timeout
(trigger period) from 0.4 seconds up to 8.5 minutes. You can make the initialization
settings in the BIOS setup. Refer to the Watchdog Settings Submenu in the Appendix B:

BIOS Operation chapter for information on configuration.

19.2 

Programming

19.2.1. 

Initialization

You can initialize the watchdog timer from the BIOS setup or the application software,
using low-level programming.

19.2.2. 

Trigger

The watchdog needs to be triggered out of the application software within the specified

timeout period. You can only do this in the application software by using low-level
programming.

For information about low-level programming for the watchdog timer, refer to Application
Note WdogP38x_E???.DOC, which you can request from Kontron technical support.
