Port C is a 6-bit general-purpose bidirectional I/O port.
The port C data register contains a data latch for each of the six port C
pins.
PTC[5:0] — Port C Data Bits
MCLK — System Clock Bit
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 system clock is driven out of PTC2 when enabled by MCLKEN in
PTC DDR7.
