Serial Status Register(SCMR.SMIF = 0 and FCR.FM=1)
| DR | Receive Data Ready flag (Valid only in asynchronous mode(including multi-processor) and FIFO selected) 0 (0): Receiving is in progress, or no received data has remained in FRDR after normally completed receiving.(receive FIFO is empty) 1 (1): Next receive data has not been received for a period after normal completed receiving, , when data is stored in FIFO to equal or less than receive triggering number. |
| Reserved | This bit is read as 0. The write value should be 0. |
| TEND | Transmit End Flag 0 (0): A character is being transmitted. 1 (1): Character transfer has been completed. |
| PER | Parity Error Flag 0 (0): No parity error occurred. 1 (1): A parity error has occurred. |
| FER | Framing Error Flag 0 (0): No framing error occurred. 1 (1): A framing error has occurred. |
| ORER | Overrun Error Flag 0 (0): No overrun error occurred 1 (1): An overrun error has occurred |
| RDF | Receive FIFO data full flag 0 (0): The quantity of receive data written in FRDR falls below the specified receive triggering number. 1 (1): The quantity of receive data written in FRDR is equal to or greater than the specified receive triggering number. |
| TDFE | Transmit FIFO data empty flag 0 (0): The quantity of transmit data written in FTDR exceeds the specified transmit triggering number. 1 (1): The quantity of transmit data written in FTDR is equal to or less than the specified transmit triggering number |
