Communication between MEMS mic and ADAU1701

Hello everyone,

I received an ADAU1701 evaluation board two days ago and I try to receive data from a MEMS mic which communicate with I2S( ). I am sorry if my question looks stupid but I do not understand whether or not I need to send a master clock to the DSP. The thing is that I want to send BCLK, LRCLK to the mic which sends the data to the DSP.

Thank you for your help,
