Figure 41-13. Multi-buffer Transfer with Source Address Auto-reloaded and Contiguous Destination Address

Address of
Source Layer
The transfer is similar to that shown in
The DMAC Transfer flow is shown in
b. If the buffer complete interrupt is masked (DMAC_EBCIMR.BTC[x] = ‘1’, where x is
SADDR
automatic transfer mode bit should remain enabled to keep the DMAC in Row 11 as
shown in
the channel number) then hardware does not stall until it detects a write to the buf-
fer transfer completed interrupt enable register but starts the next buffer transfer
immediately. In this case software must clear the automatic mode bit,
DMAC_CTRLBx.AUTO, to put the device into ROW 1 of
before the last buffer of the DMAC transfer has completed.
