description:
|
|
The ICS-43432 and compatible MEMS microphones output audio over an I2S
|
|
interface and require no software configuration. The only host connection
|
|
is the I2S bus. The microphone requires an I2S clock frequency between
|
|
460 kHz and 3.379 MHz and 64 clock cycles per stereo frame. Each frame
|
|
contains 32-bit slots per channel, with 24 bits carrying audio data.
|
|
A hardware pin determines whether the microphone outputs audio on the
|
|
left or right channel of the I2S frame.
