(4) Port input mode registers (PIM0, PIM1, PIM4, PIM5, PIM8, PIM14)
These registers set the input buffer of P01, P03, P04, P10, P11, P13 to P17, P43, P44, P53 to P55, P80, P81, P142,
and P143 in 1-bit units.
TTL input buffer can be selected during serial communication with an external device of the different potential.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
