Port A Data Register – PORTA
Port A Data Direction Register – DDRA
Port A Input Pins Address – PINA
The Port A Input Pins address (PINA) is not a register, and this address enables access to the
physical value on each Port A pin. When reading PORTA the Port A Data Latch is read, and
when reading PINA, the logical values present on the pins are read.
PortA as General
Digital I/O
All 8 pins in Port A have equal functionality when used as digital I/O pins.
PAn, General I/O Pin:
The DDAn bit in the DDRA register selects the direction of this pin, if
DDAn is set (one), PAn is configured as an output pin. If DDAn is cleared (zero), PAn is config-
ured as an input pin. If PORTAn is set (one) when the pin is configured as an input pin, the
MOS pull-up resistor is activated. To switch the pull-up resistor off, the PORTAn has to be
cleared (zero) or the pin has to configured as an output pin. The Port A pins are tri-stated
when a reset condition becomes active, even if the clock is not active.
Note:
n: 7,6...0, pin number.
