Description
Output data for a pin is stored when the pin function
is specified as a general purpose I/O.
Description
If this register is read while a PFDDR bit is set to 1,
the corresponding PFDR value is read. If this
register is read while a PFDDR bit is cleared to 0,
the corresponding pin state is read.
