Description
Reserved
These bits are read as an undefined value.
Output data for a pin is stored when the pin is
specified as a general purpose I/O port.
Description
Reserved
These bits are read as an undefined value.
If a port A read is performed while PADDR bits are
set to 1, the PADR values are read. If a port A read
is performed while PADDR bits are cleared to 0, the
pin states are read.
