(*) The different of I/O 8 type from I/O 16 type is the typical drive current. The typical drive
current of I/O 8 type is 8 mA, and for I/O pad 16 is 16 mA.
(**) When operating in default mode: GPIO7 is the ATA/ ATAPI reset input,
(***) When Reset pin is pulled low, the IDE bus will be in tri-state.
(****) RREF must be connected with a 510 ohm resister to ground.
