Data is not received from the MP34DT06J Mic

I am using the X-NUCLEO-CCA02M2 expansion board with the Nucleo-H755ZI-Q, and I’ve confirmed that the MP34DT06J microphone is receiving the correct clock signal. Proper VDD and ground are also supplied to the mic. However, when I probe the DOUT line with an oscilloscope, there is no data output observed. Is there something I might be overlooking?
