This section describes the standard transfer request (TR) format to initiate a DMA transfer. The TRs can support both half and full duplex with multiple dimensions. Each TR will also generate a TR response. A TR can be sent to the BCDMA either through a TR descriptor using a pass-by-reference ring or as a Direct TR submission using a pass-by-value ring.
