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 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.
