AD9393 BT656 question

We are developing an HDMI receiver with AD9393. The video stream coming through this is further processed in the grafics controller Lime from Fujitsu. There the video will be overlaid by whatever info. This is everything so far clear.

The grafics processor has a BT656 (YCrCb 4:2:2) input. Register 0x25 is to define the output formats. It has to be set to 4:2:2 format.

Now my kind of silly question, i could not get it from the datasheet:

 

What bits is the BT656 output? Most probably not [0..7] Lime is not supporting DDR, but the other bitgroups either contain only CbCr[16..23] or Y[8..15].

 

Thanks for any help.
