Description
Reserved
These bits are always read as 0, and the write value
should always be 0.
Each of these bits stores output data for the
corresponding pin that is used as a general output port.
If the port is read, the value of the corresponding bit in
this register will be read for a pin configured as a
general output port, while the state of the
corresponding pin will be read for a pin configured as a
general input port.
