(4) Pull-up resistor option registers (PU0, PU2, PU3, PU4, and PU12)
These registers are used to specify whether an on-chip pull-up resistor is connected to P00 to P03, P20 to
P23, P30 to P33, P40 to P47, P120, and P123. By setting PU0, PU2, PU3, PU4, or PU12, an on-chip pull-up
resistor can be connected to the port pin corresponding to the bit of PU0, PU2, PU3, PU4, or PU12.
PU0, PU2, PU3, PU4, and PU12 are set by using a 1-bit or 8-bit memory manipulation instruction.
Generation of reset signal set these registers to 00H.
