Section 9 I/O Ports
9.2
Port 2 is a general I/O port also functioning as a SCI3 I/O pin. Each pin of the port 2 is shown in
figure 9.2. The register settings of PMR1 and SCI3 have priority for functions of the pins for both
uses.
Port 2 has the following registers.
9.2.1
PCR2 selects inputs/outputs in bit units for pins to be used as general I/O ports of port 2.

Description
Reserved
When each of the port 2 pins P22 to P20 functions as an
general I/O port, setting a PCR2 bit to 1 makes the
corresponding pin an output port, while clearing the bit to 0
makes the pin an input port.
