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

R/W Description
0 R/W When PDDDR = 0 (input port), the input pull-up MOS
of the input pin is on when the corresponding bit is
0 R/W
set to 1.
