Figure 6-53 shows a DMA startup sequence from the backend interface. Initially, the backend requests access to the bus
by asserting BE_REQ. When granted, it writes to the four DMA registers (cycles B2–B5), writing to the control
register last. Three clock cycles after the write to the control register, the core asserts the PCI bus request and carries out
a normal DMA transfer.
