Receive Status Register
| RFO | Receive FIFO Overflow Flag 0 (0): No overrun error has occurred (default) 1 (1): A byte was received when the received FIFO was already full |
| RX_DATA | Receive Data Interrupt Flag 0 (0): No new byte is received 1 (1): New byte is received ans stored in Receive FIFO |
| RDTF | Receive Data Threshold Interrupt Flag 0 (0): Number of unread bytes in receive FIFO less than the value set by RDT[3:0] (default). 1 (1): Number of unread bytes in receive FIFO greater or than equal to value set by RDT[3:0]. |
| LRC_OK | LRC Check OK Flag 0 (0): Current LRC value does not match remainder. 1 (1): Current calculated LRC value matches the expected result (i.e. zero). |
| CRC_OK | CRC Check OK Flag 0 (0): Current CRC value does not match remainder. 1 (1): Current calculated CRC value matches the expected result. |
| CWT_ERR | Character Wait Time Error Flag 0 (0): No CWT violation has occurred (default). 1 (1): Time between two consecutive characters has exceeded the value in CHAR_WAIT. |
| RTE | Received NACK Threshold Error Flag 0 (0): Number of NACKs generated by the receiver is less than the value programmed in RTH[3:0] 1 (1): Number of NACKs generated by the receiver is equal to the value programmed in RTH[3:0] |
| BWT_ERR | Block Wait Time Error Flag 0 (0): Block wait time not exceeded 1 (1): Block wait time was exceeded |
| BGT_ERR | Block Guard Time Error Flag 0 (0): Block guard time was sufficient 1 (1): Block guard time was too small |
| PEF | Parity Error Flag 0 (0): No parity error detected 1 (1): Parity error detected |
| FEF | Frame Error Flag 0 (0): No frame error detected 1 (1): Frame error detected |
| RX_WPTR | Receive FIFO Write Pointer Value |
| RX_CNT | Receive FIFO Byte Count 0 (0): FIFO is emtpy |
