When a channel is disabled during a transfer, the channel undergoes an abort, unless it is hardware-source-synchronized with buffering enabled (DMA4_CCRi[25] BUFFERING_DISABLE = 0). If this is the case, the FIFO is drained to prevent the loss of data. For more information about this feature, see Section 18.1.4.19, FIFO Draining Mechanism.
