TMDX5515EZDSP: Mic bias in both channels of stereo input

Hi team

I want to developt an active control cancelling system for a class project and i'm looking for a DSP for this purpose.
In the scheme I want to implement there are two mic input signals and one output signal.
I had thought of using the TMDX5515EZDSP evaluation board, in which there is one stereo input and one stereo output, in which to connect in the R channel first input signal and in the L the other signal.

My doubt is if in the stereo input, both channels have bias. The codec here is TLV320AIC3204. I have seen in the specifications that it has programmable bias but I don't know if on the board the bias is routed to both channels or only to one as I have seen in this case:

Thank you very much for your help,
