Running ADC of the EP1S80?

Hi,

I am working with the EP1S80 and I don't know how I can have access to A/Ds. I know that there is a block in dsp builder for accessing A/D, but it doesn't work somehow. It seems that the pins are already connected to something else than sma input.

Is there any special configuration for running this chip, or just the clock input of the AD9433?
