Hello, if I understand correctly from the document (https://www.st.com/resource/en/application_note/an5027-interfacing-pdm-digital-microphones-using-stm32-mcus-and-mpus-stmicroelectronics.pdf), the SAI interface can only handle at most 8 PDM digital microphones. In this case, what will be the best way to deal with more than 8 PDM microphones? Thank you in advance!
