WDT1 Programming

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 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.
In order to simplify the programming code, we provide a sub function for the
programmers to implement their software. For DOS, Windows 95 or 98 and
Window NT, the sub function format is as follow:
out_port (int IOport_number, int Counter_value)
(write a zero to disable the timer)
Under DOS, Windows 95 or 98
Make a project program with wdt.cpp under Turbo C/C++.
Under Windows NT
The library installation procedure:
(1) run the setup program under NT environment.
(2) reboot the system.
You can also write your own DLL by referring the DOS source we provide.

/* n = second value. This program can auto detect which Super
I/O chip you use. */
IOport_number:0x3F0 -->W83977EF's configuration port.
