These bits store output data of a pin which is used as a
general-purpose output port. When the pin functions as
a general-purpose output port, reading the port will read
out the value of the corresponding bit of this register.

When the pin functions as a general-purpose input port,
reading the port will read out the status of the
corresponding pin.
