Port D general purpose input/output data—Data Register
Port D pins 7 through 0 are associated with data I/O lines DATA[7:0] respectively in expanded modes.
When not used with the alternative function, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
