你好，
在TRM里面，你可以找到下面的信息。
8.4.3.2.2 Channel Source Address (SRC)
The 32-bit source address parameter specifies the starting byte address of the source. For SAM in increment mode, there are no alignment restrictions imposed by EDMA3. For SAM in constant addressing mode, you must program the source address to be aligned to a 256-bit aligned address (5 LSBs of address must be 0).
