Input/Output (I/O) Ports
15.5 Port C
Port C is a 7-bit general-purpose bidirectional I/O port that shares two of
its pins with the analog-to-digital convertor module (ADC).
15.5.1 Port C Data Register
The port C data register (PTC) contains a data latch for each of the
seven port C pins.

PTC[6:0] — Port C Data Bits
These read/write bits are software-programmable. Data direction of
each port C pin is under the control of the corresponding bit in data
direction register C. Reset has no effect on port C data.
