R3 and R3IO register: R3 is an 4-bit CMOS bidirectional I/O
port (address 0C6_H). Each I/O pin can independently used as an
input or an output through the R3IO register (address 0C7_H).
In addition, Port R3 is multiplexed with various special features.
After reset, this value is “0”, port may be used as normal I/O port.

R4 and R4IO register: R4 is an 8-bit CMOS bidirectional I/O
port (address 0C8_H). Each I/O pin can independently used as an
input or an output through the R4IO register (address 0C9_H). The
on-chip pull-up resistor can be connected to them in 1-bit units
with a pull-up selection register 4 (PU4).
In addition, Port R4 is multiplexed with various special features.
After reset, this value is “0”, port may be used as normal I/O port.
