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. allOf: - $ref: dai-common.yaml# properties: compatible: enum: - invensense,ics43432 - cui,cmm-4030d-261 port: $ref: audio-graph-port.yaml# unevaluatedProperties: false required: - compatible unevaluatedProperties: false examples: - | ics43432: ics43432 { compatible = "invensense,ics43432"; port { endpoint { remote-endpoint = <&i2s1_endpoint>; dai-format = "i2s"; }; }; };
