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.

EXT_MEM_BK_SIZE

DMA access external memory block size. 0: 16 bytes. 1: 32 bytes. 2: 64 bytes. 3: reserved.
