Input/Output Ports
22.4 Port C
Port C is an 6-bit general-purpose bidirectional I/O port. Note that PTC5 is only available on 64-pin
package options.
22.4.1 Port C Data Register
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
22.4.2 Data Direction Register C
Data direction register C 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.
MCLKEN — MCLK Enable Bit
254
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 (5:0).
The system clock is driven out of PTC2 when enabled by MCLKEN bit in PTCDDR7.
This read/write bit enables MCLK to be an output signal on PTC2. If MCLK is enabled, DDRC2 has no
effect. Reset clears this bit.
1 = MCLK output enabled
0 = MCLK output disabled
