I using UVC with image sensor.

Is it possible  16bit bus swap in 8bit-data mode (not using 16bit-data)?

ex)  D0 ~ D7 <-> D8 ~ D15  , swap data.

Is it possible  with gpif designer or firmware coding  ?

It is not possible to swap it that way in the state machine. You might be able to do this in the firmware, but this will terribly affect the throughput and efficieny. It is better to connect the signals properly on the GPIF Lines.

If not, we recommend to do this swapping in your host application (if it is a custom host application designed by you)
