Can we use the VADC as fast ADC

I am curious if it is possible to use the VADC as a fast acting ADC, instead of for video.  Basically to get access to the VADC_DATAn before it gets to the Video Decoder.  We need an ADC that is in the same range as the 66.5Mbps rather than the 1Mbps general purpose ADC.

Hello Davin,

this would be great feature, but unfortunately it is not possible.

As you can see on the picture, a result from conversion goes directly to Video decoder. Only decoded data are available at the output of Video decoder. If used as fast ADC data cannot be decoded - so we do not get any output.
