32.2.13 Port D I/O Register 0 (PDIOR0)
PDIOR0 is a 16-bit readable/writable register that is used to set the pins on port D as inputs or
outputs. The PD15IOR to PD0IOR bits correspond to the PD15 to PD0 pins, respectively. The
setting of PDIOR0 is valid for the pins for which general I/O function is selected and has no effect
on the pins for which other function is selected. If a bit in PDIOR0 is set to 1, the corresponding
pin on port D functions as an output. If it is cleared to 0, the corresponding pin functions as an
input.
