When the DMA is configured to produce FIXED (keyhole) AXI burst-types, the following restrictions apply:
- The start address must be 128-bit aligned
- The size must be a multiple of 128-bits (four words)
Note: When loopback mode is used and only one SRC/DST is
configured for FIXED burst-type, the module that is configured as INCR burst-type must
adhere to the following:
- The INCR start address must be 128-bit aligned
- The INCR size must be a multiple of 128-bits (four words)
