Input/Output Ports (I/O)
Technical Data MC68HC908GR8 — Rev 4.0
216 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
