TLV320AIC3104-Q1: I2C control

Part Number: TLV320AIC3104-Q1

Tool/software:

Hi team,

My customer could not control the device by I2C until the device received I2S signal.

Is it any relationship between I2S signal and I2C control?

Regards,

Peter

    Hi Peter,

    Do you mean the I2C bus was returning NACK or just that the register writes did not take effect until I2S signal was applied?

    The I2C bus does not depend directly on I2S. Register writes should complete. However some features may not be apparent right away until I2S clocks are provided, since they provide all the internal clocking for the device. What writes were you trying to perform?

    Best regards,
