Appendix B: Watchdog Timer Function
Reference
This appendix describes the usage of the watchdog timer
(WDT) function library for the PXI-3950 controller. Watchdog
timer is a hardware mechanism to reset the system in case the
operating system or an application halts. After starting watch-
dog timer, you need to periodically reset the watchdog timer in
the application before the timer expires. Once watchdog timer
expires, a hardware-generated signal is sent to reset the sys-
tem.
