TLV320AIC3254: DC offset in ADC data

Part Number: TLV320AIC3254
Other Parts Discussed in Thread: CC3200

I have designed custom bluetooth board using TLV320AIC3254.

I found there is DC offset in ADC data(MIC input) around -585 as attached file below.

It should be around 0.

I understand , to remove DC offset, I need to use high pass filter.

But I do not know how to implement high pass filter on TLV320AIC3254,

because there is no document or no source code(script) about that.

Could you tell me how to implement that?

Best regards,
