PDR3 is a register that stores output data for port 3
pins. When PCR3 bits are set to 1, the values
stored in PDR3 are output.
When PDR3 is read while PCR3 bits are set to 1,
the values stored in PDR3 are read. If PDR3 is read
while PCR3 bits are cleared to 0, the pin states are
read regardless of the value stored in PDR3.
