2) Linked list operation
source and destination data areas.
based on the configuration of normal DMA continuous transfer. Upon completion of each
DMA transfer, the next LLI is loaded to continuously perform DMA operation
(daisy-chained operation).
To use the scatter/gather function, a series of linked lists should be created to define
The following shows a setting example:
1. Set the information for the first DMA transfer to the DMA registers.
2. Write the information for the second and subsequent transfers to the memory space of
3. To finish the linked list operation with the Nth DMA transfer, set “next LLI
