22.5.2 Linked list operation
To operate the scatter/gather function, a transfer source and destination data areas need to be
defined by creating a set of Linked Lists first.
Each setting is called LLI (LinkedList).
Each LLI controls the transfer of one block of data. Each LLI indicates normal DMA setting and
controls transfer of successive data. Each time each DMA transfer is complete, the next LLI
setting will be loaded to continue the DMA operation (Daisy Chain).
An example of the setting is shown below.
1. The first DMA transfer setting should be made directly in the DMA register.
2. The second and subsequent DMA transfer settings should be written in the addresses of the
3. To stop up to N'th DMA transfer, set "next LLI AddressX" to 0x00000000.
