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.
Description
Reserved
These bits are reserved, if read they will return an
undefined value.
If a port 6 read is performed while P6DDR bits are
set to 1, the P6DR values are read. If a port 6 read is
performed while P6DDR bits are cleared to 0, the pin
states are read.
