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 Bit 6
are set, any Mouse Interrupt or Keyboard Interrupt event will also cause the reload of previ-
ously-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.
