Description
Reserved
This bit is 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
If this bit is read, it will return an undefined value.
If a port G read is performed while PGDDR bits are
set to 1, the PGDR values are read. If a port G read
is performed while PGDDR bits are cleared to 0, the
pin states are read.
