CHAPTER 4 PORT FUNCTIONS
(4) Port input mode registers (PIMx)
PIM1 and PIM7 registers set the input buffer of P10, P11, P14, P15, P75, or P76 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.
