SPI/I2S status register
| RXP | Rx-packet available 0 (B_0x0): RxFIFO is empty or an incomplete data packet is received 1 (B_0x1): RxFIFO contains at least one data packet |
| TXP | Tx-packet space available 0 (B_0x0): not enough free space at TxFIFO to host next data packet 1 (B_0x1): enough free space at TxFIFO to host at least one data packet |
| DXP | duplex packet 0 (B_0x0): TxFIFO is Full and/or RxFIFO is Empty 1 (B_0x1): both TxFIFO has space for write and RxFIFO contains for read a single packet at least |
| EOT | end of transfer 0 (B_0x0): transfer is ongoing or not started 1 (B_0x1): transfer complete |
| TXTF | transmission transfer filled 0 (B_0x0): upload of TxFIFO is ongoing or not started 1 (B_0x1): TxFIFO upload is finished |
| UDR | underrun 0 (B_0x0): no underrun 1 (B_0x1): underrun detected |
| OVR | overrun 0 (B_0x0): no overrun 1 (B_0x1): overrun detected |
| CRCE | CRC error 0 (B_0x0): no CRC error 1 (B_0x1): CRC error detected |

| MODF | mode fault 0 (B_0x0): no mode fault 1 (B_0x1): mode fault detected. |
| SUSP | suspension status 0 (B_0x0): SPI not suspended (Master mode active or other mode). 1 (B_0x1): Master mode is suspended (current frame completed). |
| TXC | TxFIFO transmission complete 0 (B_0x0): current data transaction is still ongoing, data is available in TxFIFO or last frame transmission is on going. 1 (B_0x1): last TxFIFO frame transmission complete |
| RXPLVL | RxFIFO packing level 0 (B_0x0): no next frame is available at RxFIFO 1 (B_0x1): 1 frame is available 2 (B_0x2): 2 frames are available* 3 (B_0x3): 3 frames are available* |
| RXWNE | RxFIFO word not empty 0 (B_0x0): less than four bytes of RxFIFO space is occupied by data 1 (B_0x1): at least four bytes of RxFIFO space is occupied by data |
| CTSIZE | number of data frames remaining in current TSIZE session |
