Direct memory access controller (DMA) RM0440
416/2126 RM0440 Rev 4
12.6.2 DMA interrupt flag clear register (DMA_IFCR)
Address offset: 0x04
Reset value: 0x0000 0000
Setting the global clear bit CGIFx of the channel x in this DMA_IFCR register, causes the
DMA hardware to clear the corresponding GIFx bit and any individual flag among TEIFx,
HTIFx, TCIFx, in the DMA_ISR register.
Setting any individual clear bit among CTEIFx, CHTIFx, CTCIFx in this DMA_IFCR register,
causes the DMA hardware to clear the corresponding individual flag and the global flag
GIFx in the DMA_ISR register, provided that none of the two other individual flags is set.
Writing 0 into any flag clear bit has no effect.
