ADV7181C terminating unused pixel port pins ?

The design will run the ADV7181C in CP mode and only connect up pixel port pins P[19:12]. 

 

The main use case is to decode a SD color video with the SDP at 8 bits YCbCr. 

 

An input device is connected that has a higher than SD frequency that will be decoded using the CP and only the Y component.

 

Do the remaining Pixel Port Pins used by the CP (P[9:2]) need to be terminated ?  Or can they be left floating?

 

Please advise.
