DDRA7
Port A — Port A pins 7–0 can be used as general purpose I/O. If the data direction bits of the associated I/O pins
are set to logic level “1”, a read returns the value of the port register, otherwise the buffered pin input state is read.
PB7
Port B — Port B pins 7–0 can be used as general purpose I/O. If the data direction bits of the associated I/O
pins are set to logic level “1”, a read returns the value of the port register, otherwise the buffered pin input state
is read.
Data Direction Port A — This register controls the data direction for port A. DDRA determines whether each pin
is an input or output. A logic level “1” causes the associated port pin to be an output and a logic level “0” causes
the associated pin to be a high-impedance input.
0 Associated pin is configured as input.
1 Associated pin is configured as output.
Note: Due to internal synchronization circuits, it can take up to 2 bus clock cycles until the correct value is read
