I'm going to use the STEVAL-MIC008A Dual MP23DB01HP MEMS daughter board with the STM32N6570-DK (by connecting to CN5). I looked at the STM32N6570-DK example project MDF_AudioRecorder and noticed that for using on board MIC (only one micophone) it uses instance0 (MDF1_SDIO, Pin PE8) with the following configuration:
Bitstream Matrix: Falling front
Interleaved mode: No (which makes sense since it uses only one MEMS microphone)
Since the STEVAL-MIC008A includes two microphones that share the same data and clock lines, can I still use instance 0 to receive interleaved data (left and right channels) from the STEVAL-MIC008A, or do I need to enable instance 1 as well?
