Dti-edma.txt3 The eDMA3 consists of two components: Channel controller (CC) and Transfer
4 Controller(s) (TC). The CC is the main entry for DMA users since it is
5 responsible for the DMA channel handling, while the TCs are responsible to
6 execute the actual DMA tansfer.

19 Block copy channels mainly used for memory to memory transfers, but with
20 optional triggers a block copy channel can service peripherals by accessing
