Appendix B - Watchdog Timer
This appendix describes use of the watchdog timer (WDT) func-
tion library for the PXIe-3975 controller. The watchdog timer is a
hardware mechanism resetting the system when the operating
system or application halts. After starting, periodic reset of the
watchdog timer in the application before expiry is required. Once
the watchdog timer expires, a hardware-generated signal is sent
to reset the system.
