DA7212 Digital mic

I was trying to test digital mic input to the DA7212 evaluation board. I soldered two mic to MIC1_P (CLK)  and MIC1_N (DATA). I also enabled MICBIAS1 to 1.6V to bias the mic. When I measured waveform on CLK and DATA, I've found out CLK was good but DATA was distorted.  I am wondering maybe my settings in the smartcnavas GUI was wrong. Anyone has experince with it? What should be the settings for digital mic testing? Thanks.

That's fine. I've found the problem. The DATA line is connected to the mother board, and there are C and R on the mother board that caused the distortion. I disconnected that C and R and the digital mic input is working fine. Thanks.
