Description

I2S DMA configuration register

Fields

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.
OUTDSCR_BURST_EN

DMA outlink descriptor transfer mode configuration bit. 1: Prepare outlink descriptor with burst mode. 0: Prepare outlink descriptor with byte mode.
INDSCR_BURST_EN

DMA inlink descriptor transfer mode configuration bit. 1: Prepare inlink descriptor with burst mode. 0: Prepare inlink descriptor with byte mode.
OUT_DATA_BURST_EN

Transmitter data transfer mode configuration bit. 1: Prepare out data with burst mode. 0: Prepare out data with byte mode.
CHECK_OWNER

Set this bit to enable check owner bit by hardware.
MEM_TRANS_EN

Reserved.
