Watch Dog Timer Time-out value. Writing a non-zero value to this
register causes the counter to load the value to Watch Dog Counter
and start counting down. If the bit 7 and 6 of CR F7h are set, any
Mouse Interrupt or Keyboard Interrupt event will also cause the
reload of previously-loaded non-zero value to Watch Dog Counter
and start counting down. Reading this register returns current value
in Watch Dog Counter instead of Watch Dog Timer Time-out value.
00h: Time-out Disable
01h: Time-out occurs after 1 second/minute
02h: Time-out occurs after 2 second/minutes
03h: Time-out occurs after 3 second/minutes
……………………….......................................
FFh: Time-out occurs after 255 second/minutes
Mouse interrupt reset watch-dog timer enable
0: Watchdog timer is not affected by mouse interrupt.
1: Watchdog timer is reset by mouse interrupt.
Keyboard interrupt reset watch-dog timer enable
0: Watchdog timer is not affected by keyboard interrupt.
1: Watchdog timer is reset by keyboard interrupt.
Trigger WDTO# event. This bit is self-clearing.
WDTO# status bit
0: Watchdog timer is running.
1: Watchdog timer issues time-out event.
These bits select IRQ resource for WDTO#. (02h for SMI# event.)
0: GPIO5 is inactive.
0: GPIO4 is inactive.
0: GPIO3 is inactive.
0: GPIO2 is inactive.
