4.3.4 Port input mode registers (PIM1, PIM3, PIM5 to PIM7, PIM12)
These registers set the input buffer of P10, P11, P13, P14, P16, P17, P30, P54, P62, P63, P70, P71, P73, and P125
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.
