5.1 Watchdog Timer Configuration
The Watch Dog Timer (WDT) can monitor the system's status. Once you
give a value to WDT, the timer will begin to count down. To re-program a
new value to WDT, or move keyboard can restart the WDT. If the system is
idle or hang, it will reboot when the timer timeout.
The function of the watchdog timer is to reset the system automatically. It
contains a one-second (or one-minute) resolution down counter (in CRF4 of
logical device 8 of super I/O chip) and two Watchdog control registers
(CRF2 and CRF3 of logical device 8).
We provides the WDT function call for easy use under DOS, Windows
95/98/2000, and Windows NT, please refer the information under
X:\CHIPDRV\WDT.
