The AXI DMA core register space for Scatter/Gather Mode is shown in Table 1. The AXI DMA core register space for Direct Register mode is shown in Table 1. The AXI DMA registers are memory-mapped into non-cacheable memory space. This memory space must be aligned on an AXI word (32-bit) boundary.
Note: The AXI4-Lite write access register is updated by
the 32-bit AXI Write Data (
*_wdata
) signal, and is not impacted by the AXI
Write Data Strobe (*_wstrb
) signal. For a Write, both the AXI Write Address
Valid (*_awvalid
) and AXI Write Data Valid (*_wvalid
)
signals should be asserted together.
