These registers specify whether the on-chip pull-up resistors of P00 to P06, P10 to P17, P30, P31, P40 to P43,
P50 to P55, P70 to P77, P120, P140, or P141 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 PU0, PU1, PU3 to PU5, PU7, PU12, and PU14. 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 PU0, PU1,
PU3 to PU5, PU7, PU12, and PU14.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
