Watchdog Timer (WDT) Function Library 73
MVP-5100
Appendix C Watchdog Timer (WDT)
Function Library
This appendix describes use of the watchdog timer (WDT) func-
tion library for the MVP-5100 controller. The watchdog timer is a
hardware mechanism provided to reset the system if the operating
system or an application stalls. After starting, the watchdog timer
in the application must be periodically reset before the timer
expires. Once the watchdog timer expires, a hardware-generated
signal is sent to reset the system.
C.1 WDT with API/Windows
The WDT API library files and a demo program (incl. source code)
can be downloaded from:

To use the WDT function library for the MVP-5100, include the
header file WDT.h and linkage library WDT.lib in the C++ project.
