Special Features

8.1

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

ä

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

ä

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

ä

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

Contact Kontron for information on programming and operating the WDT.
