SAI Transmit Configuration 4 Register
| FSD | Frame Sync Direction 0 (0): Frame sync is generated externally in Slave mode. 1 (1): Frame sync is generated internally in Master mode. |
| FSP | Frame Sync Polarity 0 (0): Frame sync is active high. 1 (1): Frame sync is active low. |
| ONDEM | On Demand Mode 0 (0): Internal frame sync is generated continuously. 1 (1): Internal frame sync is generated when the FIFO warning flag is clear. |
| FSE | Frame Sync Early 0 (0): Frame sync asserts with the first bit of the frame. 1 (1): Frame sync asserts one bit before the first bit of the frame. |
| MF | MSB First 0 (0): LSB is transmitted first. 1 (1): MSB is transmitted first. |
| SYWD | Sync Width |
| FRSZ | Frame size |
| FPACK | FIFO Packing Mode 0 (00): FIFO packing is disabled 2 (10): 8-bit FIFO packing is enabled 3 (11): 16-bit FIFO packing is enabled |
| FCOMB | FIFO Combine Mode 0 (00): FIFO combine mode disabled. 1 (01): FIFO combine mode enabled on FIFO reads (from transmit shift registers). 2 (10): FIFO combine mode enabled on FIFO writes (by software). 3 (11): FIFO combine mode enabled on FIFO reads (from transmit shift registers) and writes (by software). |
| FCONT | FIFO Continue on Error 0 (0): On FIFO error, the SAI will continue from the start of the next frame after the FIFO error flag has been cleared. 1 (1): On FIFO error, the SAI will continue from the same word that caused the FIFO error to set after the FIFO warning flag has been cleared. |
