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.
These bits indicate the port pin state.
When the PIEN bit of the Port Control Register is set to “0”, this bit reads out “0”.
