5.1Watchdog Timer Configuration

The Watch Dog Timer (WDT) can monitor the system's status. Once you give a value to the WDT, the timer will begin to count down, moving the keyboard can restart the WDT. If the system is idle or hangs, it will reboot when the timer times out.

The function of the watchdog timer is to reset the system automatically. It contains a one-second (or one-minute) resolution down counter (in CRF2 of logical device 8 of super I/O chip) and two Watchdog control registers (CRF4 and CRF3 of logical device 8).

We provide WDT function calls for easy use under DOS, Windows 95/98/2000, and Windows NT, please refer to the information under

X:\CHIPDRV\WDT.
