Watchdog Timer
The Model KPXI-CON controller system implements two watchdog timers. The Intel® 6300ESB
provides one 2-stage programmable watchdog timer (WDT) and the W83627HF provides one 1-
stage programmable watchdog timer.
6300ESB Watchdog Timer
• Supports selectable prescaler – approximately 1MHz (1
µ
s to 1s) and approximately 1KHz
(1ms to 10min).
• The 2-stage WDT mode operates as follows: When the first programmed time expires
before the counter is reloaded, the WDT generates an IRQ, SMI, or SCI interrupt and loads
the second programmed value. If the host still fails to reload the WDT before the second
timeout, the WDT drives WDT_TOUT# low and resets Model KPXI-CON controller system.
W83627HF Watchdog Timer
• Watchdog timer is programmable from 1 to 255 seconds.
• Time out will generate interrupt to NMI or RESET, BIOS selectable.
LED Setting

following information:
•
System Active LED:
