Watchdog Timer

This feature is implemented in the AMD Geode CS5536 Companion Device. You can configure the
Watchdog Timer (WDT) from the BIOS setup to start after a set amount of time after power-on boot. The
application software should strobe the WDT to prevent its timeout. Upon timeout, the WDT resets and
restarts the system. This provides a way to recover from program crashes or lockups.

Configuration

Timer 1 has a range of 0 to 30 minutes and triggers NMI.

Timer 2 has a range of 0 to 30 minutes and triggers Reset.

The range of both timers by using JIDA32 is 0 to 65535 seconds.

Contact Kontron for information on programming and operating the WDT.
