10.9.2 Port D Data Register (PDDR)
PDDR stores output data for port D pins.
Bit Bit Name Initial Value R/W Description
7 PD7DR 0 R/W
6 PD6DR 0 R/W
5 PD5DR 0 R/W
4 PD4DR 0 R/W
3 PD3DR 0 R/W
2 PD2DR 0 R/W
1 PD1DR 0 R/W
Output data for a pin is stored when the pin is
specified as a general purpose output port.
0 PD0DR 0 R/W
10.9.3 Port D Register (PORTD)
PORTD shows port D pin states. This register cannot be modified.

If a port D read is performed while PDDDR bits are
set to 1, the PDDR values are read. If a port D read is
performed while PDDDR bits are cleared to 0, the pin
states are read.
