These registers specify whether the on-chip pull-up resistors 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 these registers. 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 these registers.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H (sets only PU12 to 20H).
