    Hi, Harvinder,

    Please take a look at the attached .zip file. It contains some examples of the register configuration for digital microphones.

    Digital microphone data must be connected to SCLK and digital microphone clock must be connected to MISO. As mentioned in the application reference guide, there are multiple ways to configure the digital microphone in case you need an alternative connection.
