8-bit input/output port.
Input/output mode can be specified bit-wise.
If used as an input port, on-chip pull-up resistor can be used by software.
Port 13.

If used as an input port, on-chip pull-up resistor can be used by software.
Cautions For pins which have alternate functions as port output (See 4.1.1 Normal operating mode pins,
(1) Port Pins), do not execute the following operations during A/D conversion. If performed,
then the general error standards cannot be maintained during A/D conversion.
<1> If it is used as a port, rewriting the output latch of its output.
<2> Even if it is not used as a port, changing the output level of pins used as outputs.
