SAI Transmit Configuration 4 Register
| FSD | Frame Sync Direction 0 (FSD_0): Frame sync is generated externally in Slave mode. 1 (FSD_1): Frame sync is generated internally in Master mode. |
| FSP | Frame Sync Polarity 0 (FSP_0): Frame sync is active high. 1 (FSP_1): Frame sync is active low. |
| ONDEM | On Demand Mode 0 (ONDEM_0): Internal frame sync is generated continuously. 1 (ONDEM_1): Internal frame sync is generated when the FIFO warning flag is clear. |
| FSE | Frame Sync Early 0 (FSE_0): Frame sync asserts with the first bit of the frame. 1 (FSE_1): Frame sync asserts one bit before the first bit of the frame. |
| MF | MSB First 0 (MF_0): LSB is transmitted first. 1 (MF_1): MSB is transmitted first. |
| CHMOD | Channel Mode 0 (CHMOD_0): TDM mode, transmit data pins are tri-stated when slots are masked or channels are disabled. 1 (CHMOD_1): Output mode, transmit data pins are never tri-stated and will output zero when slots are masked or channels are disabled. |
| SYWD | Sync Width |
| FRSZ | Frame size |
| FPACK | FIFO Packing Mode 0 (FPACK_0): FIFO packing is disabled 2 (FPACK_2): 8-bit FIFO packing is enabled 3 (FPACK_3): 16-bit FIFO packing is enabled |
| FCONT | FIFO Continue on Error 0 (FCONT_0): On FIFO error, the SAI will continue from the start of the next frame after the FIFO error flag has been cleared. 1 (FCONT_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. |
