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.
