The Linked List multi-buffer transfer is initiated by programming DMAC_DSCRx with DSCRx(0)
(LLI(0) base address) different from zero. Other fields and registers are ignored and overwritten
when the descriptor is retrieved from memory.
The last transfer descriptor must be written to memory with its next descriptor address set to 0.
