5 Special Features
5.1 Watchdog Timer
This feature is implemented in the Winbond 83627HF super I/O. 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 (Refer to Appendix F: JIDA Standard). 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.
