(4) Port input mode registers (PIM3, PIM7, PIM8)

Symbol
PIM3
PIM7
PIM8
The PIM3 and PIM7 registers set the input buffer of P31, P32, P71, P72, P74, or P75 in 1-bit units.
TTL input buffer can be selected during serial communication with an external device of the different potential.
The PIM8 register is used to enable or disable the digital inputs to P80 to P83 in 1-bit units. When using a
comparator or a programmable gain amplifier, the digital inputs are disabled (used as analog input) by software
processing. To use port functions and alternative functions, the digital inputs must be enabled, because they are
disabled (used as analog input) by default.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
Note In the case of the 40-pin product, be sure to clear PIM82 bit of the PIM8 register to “0”.
