1 Invensense ICS-43432 MEMS microphone with I2S output.
3 There are no software configuration options for this device, indeed, the only
4 host connection is the I2S interface. Apart from requirements on clock
5 frequency (460 kHz to 3.379 MHz according to the data sheet) there must be
6 64 clock cycles in each stereo output frame; 24 of the 32 available bits
7 contain audio data. A hardware pin determines if the device outputs data
8 on the left or right channel of the I2S frame.
