The DMAC Transfer flow is shown in
18. The DMAC fetches the next LLI from memory location pointed to by the current
SADDR
detect when the transfer is complete. If the DMAC is not in Row 1 as shown in
1 on page
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
