Bits 31:28, 15:12 Reserved, must be kept at reset value.

Bits 27, 21, 11, 5 CTCIFx: stream x clear transfer complete interrupt flag (x = 3 to 0)

Writing 1 to this bit clears the corresponding TCIFx flag in the DMA_LISR register.

Bits 26, 20, 10, 4 CHTIFx: stream x clear half transfer interrupt flag (x = 3 to 0)

Writing 1 to this bit clears the corresponding HTIFx flag in the DMA_LISR register

Bits 25, 19, 9, 3 CTEIFx: Stream x clear transfer error interrupt flag (x = 3 to 0)

Writing 1 to this bit clears the corresponding TEIFx flag in the DMA_LISR register.

Bits 24, 18, 8, 2 CDMEIFx: stream x clear direct mode error interrupt flag (x = 3 to 0)

Writing 1 to this bit clears the corresponding DMEIFx flag in the DMA_LISR register.

Bits 23, 17, 7, 1 Reserved, must be kept at reset value.

Bits 22, 16, 6, 0 CFEIFx: stream x clear FIFO error interrupt flag (x = 3 to 0)

Writing 1 to this bit clears the corresponding CFEIFx flag in the DMA_LISR register.
