Working Around the Byte Ordering

Question: Is it possible to exchange the byte ordering on the FD lines of FX2 to match that of FX?

 

Answer:

In FX2 the first byte in the endpoint always goes out FD[7:0] and the second byte always goes out FD[15:8]. You must take care to wire the data lines appropriately to your device to achieve the necessary ordering:


FD[7:0] -> second byte port on device
FD[15:8] -> first byte port on device
