Description
Reserved
These bits are undefined and cannot be modified.
Store output data for a pin that functions as a general
output port.
Description
Reserved
These bits are undefined.
If the port A is read while PADDR bits are set to 1, the
PADR value is read. If the port A is read while PADDR
bits are cleared to 0, the pin states are read.
