Input/Output (I/O) Ports
16.5 Port C
Port C is a 7-bit, general-purpose bidirectional I/O port. Port C also has
software configurable pullup devices if configured as an input port.
16.5.1 Port C Data Register
The port C data register (PTC) contains a data latch for each of the
seven port C pins.
NOTE: Bit 6 and bit 5 of PTC are not available in a 40-pin dual in-line package
and 42-pin shrink dual in-line package.
