Description
Reserved
If this bit is read, it will return an undefined value.
If this register is read while a PGDDR bit is set to 1,
the corresponding PGDR value is read. If this
register is read while a PGDDR bit is cleared to 0,
the corresponding pin state is read.
Description
Reserved
This bit is always read as 0, and cannot be
modified.
Output data for a pin is stored when the pin function
is specified as a general purpose I/O.
