1Invensense ICS-43432-compatible MEMS microphone with I2S output.
2
3There are no software configuration options for this device, indeed, the only
4host connection is the I2S interface. Apart from requirements on clock
5frequency (460 kHz to 3.379 MHz according to the data sheet) there must be
664 clock cycles in each stereo output frame; 24 of the 32 available bits
7contain audio data. A hardware pin determines if the device outputs data
8on the left or right channel of the I2S frame.
