(3) Pull-up resistor option registers (PU0, PU1, PU3, PU7, PU12)

These registers specify whether the on-chip pull-up resistors of P00, P01, P10 to P17, P30 to P33, P70 to P76,
and P120 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, PU7, and
PU12. 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, PU7, and PU12.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to 00H.
