DO DMA in Handshake Mode
For the DO pattern generation operation in handshake mode,
PCIe-7360 card can generate output data to external devices by
handshake data transfer through DO-REQ output signal and
DO-ACK input signal of AFI interface. The operation sequences
are listed as follows:
Step1: Configuration
X
Define DO port configuration (32/24/16/8-bits data width)
X
Define DO logic level configuration (3.3/2.5/1.8V)
X
Define DO-REQ and DO-ACK signal (AFI0 to AFI7)
Z
For example: if configure AFI3 as DO-REQ and AFI4 as
DO-ACK, and then you must connect the handshake sig-
