    Hi, Jithin,

    The digital microphone configuration requires of DIN, MISO, SCLK and/or GPIO pins. These pins are configured as digital microphone clock and data. Unfortunately, the TLV320AIC3254EVM-U doesn't have these pins available for this feature. I would recommend to use the TLV320AIC3254EVM-K. This EVM is used to test all the functions of the TLV320AIC3254. Normally, the TLV320AIC3254EVM-U is used for plug and play applications.

    In order to configure the audio codec properly, I would recommend to take a look at the following scripts. They contain some examples for digital and analog microphone configurations:

    Please let me know if you have additional questions or comments.

    Best regards,
    Luis Fernando Rodríguez S.
