Linked List Mode
Linked list mode requires the software to allocate buffers and setup a list of descriptors for
each buffer. Once this is done the software writes DMAxLAR with the address of the first
descriptor. After the DMAxLAR is written, the DMA reads the first descriptor into the
DMA control and address registers with the exception of the LAR data. It executes the
transfers as specified by the descriptor data in the DMA. When the transfers are complete,
the DMA reads in the next descriptor in the list and continue executing transfers.
Figure 58
on page 278 displays two descriptors and two sets of destination and source buf-
fers. It also displays how the descriptors are loaded into the DMA and then executed.
