| DNU | Do not use | Do not use these connections for PCB signal routing channels. Do not connect any host system signal to these connections. |
| NC | Not connected | The connection may safely be used for routing space for a signal on a PCB. However, any signal connected to an NC pin must not have voltage levels higher than VIO. |
| RFU | Reserved for Future use | Do not use RFU connectors for PCB routing channels so that the PCB may take advantage of future enhanced features in devices with a compatible footprint. |
| SCB | Serial Control Block | A peripheral that can be used as I2C, UART or SPI |
