Watchdog Timer
The cPCI-6841 implements a watchdog timer (WDT) using the
Winbond W83627HF Super I/O. The programmable I/O port is on
address 2E, and the timer can be set for 1 to 255 seconds or 1 to
255 minutes. Easy-programming libraries for DOS and Windows
95/98/NT are included.
Hardware Monitoring
The cPCI-6841 uses the Winbond W83627HF Super I/O to detect
system voltages and temperatures. When it detects that the volt-
ages or temperatures out of the safety range, it will instruct the
southbridge ICH4 to send the signals out halting the system in
order to protect the CPU board.
