Stores output data for port 5 pins.
If PDR5 is read while PCR5 bits are set to 1, the value
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.

Only bits for which PCR5 is cleared are valid. The pull-up
MOS of the corresponding pins enter the on-state when
these bits are set to 1, while they enter the off-state when
these bits are cleared to 0.
