Figure 41-13. Multi-buffer Transfer with Source Address Auto-reloaded and Contiguous Destination Address
6438G–ATARM–19-Apr-11
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.
