The port pins, P0 ~ P6, automatically turn to input/output ports by setting to 8-bit bus interface mode
(controlled by HWR/BYTE pin). When set to 16-bit bus interface mode, all functions of this register become
invalid. Further, the writing into this register at 16-bit bus interface mode becomes invalid while the reading
becomes H’0000.
