Port A Output Data Register (PAODR)
PAODR is an 8-bit readable/writable register that stores output data for the port A pins (PA7 to
PA0). PAODR can always be read or written to, regardless of the contents of PADDR.
PAODR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.
Port A Input Data Register (PAPIN)
Note:
Reading PAPIN always returns the pin states.
