9.9
Port C is a general I/O port also functioning as an external oscillation pin and clock output pin.
Each pin of the port C is shown in figure 9.9. The register setting of CKCSR has priority for
functions of the pins for both uses.
Port C has the following registers.

Description
Reserved
When each of the port C pins, PC1 and PC0, functions as
an general I/O port, setting a PCRC bit to 1 makes the
corresponding pin an output port, while clearing the bit to
0 makes the pin an input port.
