Is the DCMI capable of acquiring 12-bit raw bayer image data?

The data sheet of the STM32F429 shows that its camera interface can take 14-bit parallel data and the maximum data rate is 54MB/s. Also it says the interface supports 8-bit progressive video monochrome or raw bayer format, without mentioning higher bitdepth. I wonder if it does imply that you can't capture 10-bit or 12-bit raw bayer image data with the DCMI.

I believe it is agnostic to the form of the data

The table 18 on the following document shows 14-bit raw bayer format is supported. But I'm not sure why the data sheet doesn't mention 10, 12, 14-bit.

Also it's strange that the ST wrote '8/10, 12, 14 bits progressive video (monochrome or raw bayer) '. What does '8/10' mean...?  Why are there two same items in the 'supported data format' box?

8 or 10-bit modes
