Step2: Execute DI DMA Read Command (burst handshake mode)
X
PCIe-7360 will generate DI-ACK signal when it is ready to
receive DI data after DI-REQ signal is active.
X
External device starts to send DI data and DI sample clock
after DI-ACK signal is active.
X PCIe-7360 starts to receive DI data and DI sample clock
from external device when DI-REQ and DI-ACK are all
active.
X
The DI data in the DI FIFO is transferred into system mem-
ory directly and automatically by bus mastering DMA.
The operating architecture of DI DMA in burst handshake mode is
as shown.
