PDR9 is a register that stores output data for port 9
pins. When PCR9 bits are set to 1, the values
stored in PDR9 are output.
When PDR9 is read while PCR9 bits are set to 1,
the values stored in PDR9 are read. If PDR9 is read
while PCR9 bits are cleared to 0, the pin states are
read regardless of the value stored in PDR9.
