Using DCMI in interlaced scans

I am working on an application which requires interfacing an analog camera. I have choosed TI TVP5150AM1 to decode analog video to YCrCb 4:2:2 format and the scan format will be interlaced. As it has been mention here… DCMI is capable of working with progressive scans, but I need to use it in interlaced scan. As it uses VSYNC signal to detect the end of a frame, seems doesn't care about count of lines (whether 625 or 312), but I need to make sure that it does work with interlaced scan.

Does it work?


P.S: Ah, I need to mention that I use odd/even frames as two seperate frames, therefore it is not required to combine odd and even frames into each other to reproduce the image.
