SAI status register
| OVRUDR | Overrun / underrun. 0 (B_0x0): No overrun/underrun error. 1 (B_0x1): Overrun/underrun error detection. |
| MUTEDET | Mute detection. 0 (B_0x0): No MUTE detection on the SD input line 1 (B_0x1): MUTE value detected on the SD input line (0 value) for a specified number of consecutive audio frame |
| WCKCFG | Wrong clock configuration flag. 0 (B_0x0): Clock configuration is correct 1 (B_0x1): Clock configuration does not respect the rule concerning the frame length specification defined in Section 59.4.6: Frame synchronization (configuration of FRL[7:0] bit in the SAI_xFRCR register) |
| FREQ | FIFO request. 0 (B_0x0): No FIFO request. 1 (B_0x1): FIFO request to read or to write the SAI_xDR. |
| CNRDY | Codec not ready. 0 (B_0x0): External AC’97 Codec is ready 1 (B_0x1): External AC’97 Codec is not ready |
| AFSDET | Anticipated frame synchronization detection. 0 (B_0x0): No error. 1 (B_0x1): Frame synchronization signal is detected earlier than expected. |
| LFSDET | Late frame synchronization detection. 0 (B_0x0): No error. 1 (B_0x1): Frame synchronization signal is not present at the right time. |
| FLVL | FIFO level threshold. 0 (B_0x0): FIFO empty (transmitter and receiver modes) 1 (B_0x1): FIFO less than or equal to 1/4 but not empty (transmitter mode), FIFO less than 1/4 but not empty (receiver mode) 2 (B_0x2): 1/4 less than FIFO less than or equal to 1/2 (transmitter mode), 1/4 less than or equal to FIFO less than 1/2 (receiver mode) 3 (B_0x3): 1/2 less than FIFO less than or equal to 3/4 (transmitter mode), 1/2 less than or equal to FIFO less than 3/4 (receiver mode) 4 (B_0x4): 3/4 less than FIFO but not full (transmitter mode), 3/4 less than or equal to FIFO but not full (receiver mode) 5 (B_0x5): FIFO full (transmitter and receiver modes) |
