The DMAC Transfer flow is shown in

DMAC_DSCRx register, and automatically reprograms the DMAC_DADDRx,
DMAC_CTRLAx, DMAC_CTRLBx and DMAC_DSCRx channel registers. Note that the
DMAC_SADDRx is not re-programmed as the reloaded value is used for the next
DMAC buffer transfer. If the next buffer is the last buffer of the DMAC transfer then the
DMAC_CTRLBx and DMAC_DSCRx registers just fetched from the LLI should match
