Description
Reserved
These bits are always read as 0 and cannot be
modified.
An output data for a pin is stored when the pin
function is specified to a general purpose I/O.

If a port 6 read is performed while P6DDR bits are
R
set to 1, the P6DR values are read. If a port 6 read
is performed while P6DDR bits are cleared to 0, the
R
pin states are read.
