Figure 19-8. Multi-Block with Linked List Address for Source and Destination
If the user needs to execute a DMA transfer where the source and destination address are con-
tiguous but the amount of data to be transferred is greater than the maximum block size
CTLx.BLOCK_TS, then this can be achieved using the type of multi-block transfer as shown in
Figure 19-9 on page
transfer continues until the DMACA determines that the CTLx and LLPx registers at the
end of a block transfer match that described in Row 1 or Row 5 of
326. The DMACA then knows that the previous block transferred was the last block in
the DMA transfer. The DMA transfer might look like that shown in
331.
