I2S DMA configuration register
IN_RST | Set this bit to reset in-DMA FSM. Set this bit before the DMA configuration. |
OUT_RST | Set this bit to reset out-DMA FSM. Set this bit before the DMA configuration. |
AHBM_FIFO_RST | Set this bit to reset AHB interface cmdFIFO of DMA. Set this bit before the DMA configuration. |
AHBM_RST | Set this bit to reset AHB interface of DMA. Set this bit before the DMA configuration. |
OUT_LOOP_TEST | Set this bit to loop test inlink. |
IN_LOOP_TEST | Set this bit to loop test outlink. |
OUT_AUTO_WRBACK | Set this bit to enable outlink-written-back automatically when out buffer is transmitted done. |
OUT_NO_RESTART_CLR | Reserved. |
OUT_EOF_MODE | DMA out EOF flag generation mode. 1: When DMA has popped all data from the FIFO. 0: When AHB has pushed all data to the FIFO. |
