Transactions that hit the PCIe to DMA space are routed to the DMA Subsystem for the PCIeXDMA Subsystem internal configuration register bus. This bus supports 32 bits of address space and 32-bit read and write requests.

XDMA registers can be accessed from the host or from the AXI Slave interface. These registers should be used for programming the DMA and checking status.
