Like a nonlinked-list transfer, a link transfer starts under host control by enabling the associated logical channel (set the DMA4_CCRi[7] ENABLE bit to 1). The DMA4_CDPi[10] FAST bit sets the start mode of the link-list transfer:
In nonfast-start mode, the logical channel configuration is fully initialized so that the transfer can start without descriptor loading.
In fast-start mode, the descriptor pointer and other inputs are given. The channel starts by loading the descriptor and then starts the data transfer phase.
