5 Special Features

5.1 Watchdog Timer

This feature is implemented in the Xilinx XC9536XL microcontroller. 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.
