(3) Pull-up resistor option registers (PUxx)
Symbol
PU12
PU1
PU3
PU4
PU5
These registers specify whether the on-chip pull-up resistors of PUxx are to be used or not. On-chip pull-up
resistors can be used in 1-bit units only for the bits set to input mode of the pins to which the use of an on-chip
pull-up resistor has been specified in PUxx. On-chip pull-up resistors cannot be connected to bits set to output
mode and bits used as alternate-function output pins, regardless of the settings of Pull-up resistor option registers.
Pull-up resistor option registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
