MIG v3.4-v3.7 Virtex6 QDRII+ - Why are there two sets of signals on the client interface?

Description

There two sets of signals on the client interface that end in 0 or 1. What are they for?

Solution

To accommodate burst length 2 devices, the client interface contains ports for two read and two write transactions. When using burst length 4, only the ports ending in 0 should be used. However, MIG only supports BL=4, so you must only use the ports ending in 0.
