Function:
Address:
Port C is an 8-bit general-purpose bidirectional I/O port with software
configurable pullups and current drive options.
The port C data register contains a data latch for each of the eight port C
pins.
PTC7–PTC1 are not available in the 20-pin PDIP, 20-pin SOIC, and
28-pin SOIC packages.
PTC[7:0] — Port C Data Bits

Read:
Write:
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.
The port C pullup enable bit, PCP, in the port option control register
(POCR) enables pullups on port C pins if the respective pin is
configured as an input. (See
