Indicates the MSB 32 bits of the source address AXI DMA reads from to transfer data to AXI4-Stream on the MM2S Channel. Note: If Data Realignment Engine is included, the Source Address can be at any byte offset. If Data Realignment Engine is not included, the Source Address must be MM2S Memory Map data width aligned. |
