It supports Bayer RGGB8, which should be basically unprocessed data off of the CMOS. I can't imagine it being useful though. It would require unBayerizing it to display, even though the XO's display is also Bayer (I assume pixel offsets and swizzling would mess it up, even if the colors are in the same order). You're better off letting the camera do the heavy processing and just get packed RGB back.
