These registers set the input buffer in 1-bit units.  

TTL input buffer can be selected during serial communication with an external device of the different potential. 

Port input mode registers can be set by a 1-bit or 8-bit memory manipulation instruction. 

Reset signal generation clears these registers to 00H.
