Description
Reserved
This bit is always read as 1.
These bits store output data for port 7 pins.
If PDR7 is read while PCR7 bits are set to 1, the value
stored in PDR7 is read. If PDR7 is read while PCR7 bits
are cleared to 0, the pin states are read regardless of the
value stored in PDR7.
Reserved
These bits are always read as 1.
