Port x Data Register. Values written to this 8-bit read/write register will be
output on port x pins if the corresponding data direction bits are set HIGH (port
output). Values read from this register reflect the external state of Port x
inputs. All bits are cleared by a system reset. (“X.” stands for a letter, A
through H.)

Port x Data Direction Register. Bits cleared in this 8-bit read/write register will
select the corresponding pin in port x to become an input, setting a bit sets the
pin to output. All bits are cleared by a system reset. (“X.” stands for a letter, A
through H.)
