based on the configuration of normal DMA continuous transfer. Upon completion of each
DMA transfer, the next LLI is loaded to continuously perform DMA opration (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
