Bits 31:28, 15:12 Reserved, must be kept at reset value.
Bits 27, 21, 11, 5 TCIFx: stream x transfer complete interrupt flag (x = 7 to 4)
This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the
DMA_HIFCR register.
0: no transfer complete event on stream x
1: a transfer complete event occurred on stream x
Bits 26, 20, 10, 4 HTIFx: stream x half transfer interrupt flag (x = 7 to 4)
This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the
DMA_HIFCR register.
0: no half transfer event on stream x
1: a half transfer event occurred on stream x
Bits 25, 19, 9, 3 TEIFx: stream x transfer error interrupt flag (x = 7 to 4)
This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the
DMA_HIFCR register.
0: no transfer error on stream x
1: a transfer error occurred on stream x
Bits 24, 18, 8, 2 DMEIFx: stream x direct mode error interrupt flag (x = 7 to 4)
This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the
DMA_HIFCR register.
0: no direct mode error on stream x
1: a direct mode error occurred on stream x
Bits 23, 17, 7, 1 Reserved, must be kept at reset value.
Bits 22, 16, 6, 0 FEIFx: stream x FIFO error interrupt flag (x = 7 to 4)
This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the
DMA_HIFCR register.
0: no FIFO error event on stream x
1: a FIFO error event occurred on stream x
