When each of the port 5 pins P57 to P50 functions as a
general I/O port, setting a PCR5 bit to 1 makes the
corresponding pin an output port, while clearing the bit
to 0 makes the pin an input port.

PDR5 stores output data for port 5 pins.
If PDR5 is read while PCR5 bits are set to 1, the values
stored in PDR5 are read. If PDR5 is read while PCR5
bits are cleared to 0, the pin states are read regardless
of the value stored in PDR5.
