These registers specify whether the on-chip pull-up resistors of P12, P13, P31 to P34, P40, P100, P101, P112,
P113, P120, P140 to P143, or P150 to P153 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 PU1, PU3, PU4, PU10 to PU12, PU14, and PU15. 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 PU1, PU3,
PU4, PU10 to PU12, PU14, and PU15.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
