7.5 Port C
7.5.1 Port C Data Register
MC68HC705C8A — Rev. 3
MOTOROLA
Address:
Port C is an 8-bit, general-purpose, bidirectional I/O port. PC7 has a high
current sink and source capability.
The port C data register (PORTC) shown in
latch for each of the eight port C pins. When a port C pin is programmed
to be an output, the state of its data register bit determines the state of
the output pin. When a port C pin is programmed to be an input, reading
the port C data register returns the logic state of the pin.
PC7–PC0 — Port C Data Bits

Read:
Write:
These read/write bits are software programmable. Data direction of
each bit is under the control of the corresponding bit in data direction
register C. PC7 has a high current sink and source capability. Reset
has no effect on port C data.
