Chapter 21
Watchdog Timer
21. Watchdog Timer
The watchdog timer of the MOPSlcdLX can issue a reset to the system. The watchdog timer circuit has to be
triggered within a specified time by the application software. If the watchdog is not triggered because
proper software execution fails or a hardware malfunction occurs, it will reset the system.
21.1 Programming
21.1.1 Initialization
You can initialize the watchdog timer from the BIOS Setup. You also can set up the initialization from the
application software with help of the JIDA (Jumptec Intelligent Device Architecture) programmer's inter-
face.
21.1.2 Trigger
The watchdog needs to be triggered out of the application software within a specified timeout period. You
can only do this in the application software by using low-level programming or with help of the JIDA pro-
grammer's interface.
For information about the JIDA programmer's interface refer to the JIDA software packages on the Kontron
Web site.
