Port D
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors.
Three I/O memory address locations are allocated for Port D, one each for the Data
Register – PORTD, $12, Data Direction Register – DDRD, $11 and the Port D Input Pins
– PIND, $10. The Port D Input Pins address is read-only, while the Data Register and
the Data Direction Register are read/write.
The Port D output buffers can sink 10 mA. As inputs, Port D pins that are externally
pulled low will source current if the pull-up resistors are activated.
Port D as General Digital I/O
All eight pins in Port D have equal functionality when used as digital I/O pins.
PDn, general I/O pin: The DDDn bit in the DDRD register selects the direction of this pin.
If DDDn is set (one), PDn is configured as an output pin. If DDDn is cleared (zero), PDn
is configured as an input pin. If PDn is set (one) when configured as an input pin, the
MOS pull-up resistor is activated. To switch the pull-up resistor off, the PDn has to be
cleared (zero), or the pin has to be configured as an output pin. The port pins are tri-
stated when a reset condition becomes active, even if the clock is not running.
