Watchdog Timer (WDT) Function Library 77
MXC-6000
Appendix D: Watchdog Timer (WDT)
Function Library
This appendix describes use of the watchdog timer (WDT) func-
tion library for the MXC-6000 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.
D.1 WDT with API/Windows
Matrix WDT API library files and a demo program (incl. source
code) can be found on the included driver CD or downloaded from
http://www.adlinktech.com.
To use the WDT function library for MXC-6000 series, include the
header file WDT.h and linkage library WDT.lib in the C++ project.
