• BTSIZE
Buffer Transfer Size. The transfer size relates to the number of transfers to be performed, that is, for writes it refers to the
number of source width transfers to perform when DMAC is flow controller. For Reads, BTSIZE refers to the number of
transfers completed on the Source Interface. When this field is set to 0, the DMAC module is automatically disabled when
the relevant channel is enabled.
• SCSIZE
Source Chunk Transfer Size.
• DCSIZE
Destination Chunk Transfer size.
• SRC_WIDTH
