Watchdog Timer

You can configure the Watchdog Timer (WDT) in BIOS setup to start after a set amount of time after power-on boot. The
WDT can also be controlled by the JIDA32 Library API. 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

You can program the timeout period for the watchdog timer in two ranges:

» 1-second increments from 1 to 255 seconds

» 1-minute increments from 1 to 255 minutes

Contact Kontron Embedded Modules technical support for information on programming and operating the WDT.
