ADAU1761 Inputs

Hey all,

 

I'm currently using the BF706 Evaluation Board with the ADAU1761 Codec on it. I'm trying to take in an input sinusoid and plot the samples using CCES. Unfortunately when I try and plot the buffer (which has 64 samples), the resulting plot values don't make any sense - the plot only jumps between 0 and 2^32 (with a little bit of noise variation). 

 

I was hoping to instead take my results directly from the ADC output, and plot those individually, but I was wondering what register the ADC outputs its values to? Otherwise, does anyone know a better method for me to obtain the input sinusoid? 

 

I understand that this is probably a very simple question and I'd greatly appreciate any input anyone may have.
