DESCRIPTION
7/0
R/W
Watchdog Timer I Time-out value. Writing a non-zero value to
this register causes the counter to load the value into the Watch
Dog Counter and start counting down. If CR F2h, bits 7 and 6 are
set, any Mouse Interrupt or Keyboard Interrupt event causes the
previously-loaded, non-zero value to be reloaded to the Watch
Dog Counter and the count down resumes. Reading this register
returns the current value in the Watch Dot Counter, not the
Watch Dog Timer Time-out value.
00h: Time-out Disable
01h: Time-out occurs after 5.03x10
