PortD as General
Digital I/O
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 con-figured as an output pin. If DDDn is cleared (zero), PDn is con-
figured as an input pin. If PORTDn 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 PORTDn has to be
cleared (zero) or the pin has to configured as an output pin. The Port D pins are tri-stated
when a reset condition becomes active, even if the clock is not active.
Note:
n: 7, 6...0, pin number.
