Note :
Some pins are initialized by open-drain output mode, when the device is reset. Because the
pins are hided in 16 pin package and it is stable that hided pins are be in open-drain-output
mode.
The reset status of MC81F4x16 is designed under consideration of 16 pin package of
MC81F4204. Because MC81F4204 is a reduced version of MC81F4x16. (So the
Eva.board(emulator) is shared)
