12.4.2 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.
DDRC6–DDRC0 — Data Direction Register C Bits
These read/write bits control port C data direction. Reset clears
DDRC6–DDRC0, configuring all port C pins as inputs.
1 = Corresponding port C pin configured as output
0 = Corresponding port C pin configured as input
NOTE:
Avoid glitches on port C pins by writing to the port C data register before changing
data direction register C bits from 0 to 1.
Figure 12-11 shows the port C I/O logic.
NOTE:
For those devices packaged in a 42-pin shrink dual in-line package, PTC5 and
PTC6 are connected to ground internally. DDRC5 and DDRC6 should be set to a 0
to configure PTC5 and PTC6 as inputs.
