| PODR | Port Output Data 0 (0): Low output 1 (1): High output |
| PIDR | Port Input Data 0 (0): Low input 1 (1): High input |
| PDR | Port Direction 0 (0): Input (Functions as an input pin.) 1 (1): Output (Functions as an output pin.) |
| Reserved | This bit is read as 0. The write value should be 0. |
| PCR | Pull-up Control 0 (0): Disables an input pull-up. 1 (1): Enables an input pull-up. |
| Reserved | This bit is read as 0. The write value should be 0. |
| NCODR | N-Channel Open Drain Control 0 (0): CMOS output 1 (1): NMOS open-drain output |
| Reserved | This bit is read as 0. The write value should be 0. |
