Input/Output Ports (I/O)

MOTOROLA

16.5 Port C

Port C is a 2-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 two

port C pins.

PTC1–PTC0 — 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.

NOTE:

PTC is not available in a 28-pin DIP and SOIC package
