Input/Output (I/O) Ports
13.5 Port C
Port C is a 7-bit, general-purpose bidirectional I/O port. Port C also has software configurable pullup
devices if configured as an input port.
13.5.1 Port C Data Register
The port C data register (PTC) contains a data latch for each of the seven port C pins.
PTC6–PTC0 — Port C Data Bits
CAN
13.5.2 Data Direction Register C
Data direction register C (DDRC) determines whether each port C pin is an input or an output. Writing a
logic 1 to a DDRC bit enables the output buffer for the corresponding port C pin; a logic 0 disables the
output buffer.

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 CAN
MSCAN08 control register determines, whether the PTC1/CAN
pins or general-purpose I/O pins. See
