output key matrix signals.
If this port is set to the input mode when a key matrix is not used,
it functions as a CMOS input port to/from which a resistor can be
connected/disconnected in 1-bit units. If this port is set in the
output mode when a key matrix is not used, it functions as a high-
current CMOS output port.
