Part Number: TLV320AIC3101
My customer want to use TLV320AIC3101 as Analog(ADC) to I2S, or I2S to analog(DAC) converter. Could you tell me how to set the registers(let me know which register we should change for the settings)?
I see that the E2E title refers to I2C communication and the description mentions I2S. If it is for I2S, the register settings are 00. Kindly note, the reset value is 00, therefore I2S is set by default. Please refer to section 11.6 Register Maps (Table 15) in the TLV320AIC3101 datasheet for additional details.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Valerie Vidal:
Thanks for your prompt response and sorry for my type on the title, I meat I2S, not I2C.
I'm not asking about how to set digital signal format. My customer want to know how to set the internal paths highlighted red and blue as below.Could you check that to the expert of audio codec devices?
Also, I want to know how generated WCLK and BCLK from external I2S master are handled inside the device.
In reply to Takashi Onawa:
Thanks for your reply.
These paths are already enabled. SW-D1 and SW-D2 are only closed if both DACs are powered down. The Left ADC is routed to DOUT and DINL is routed to the Left DAC.
Hope this answers your question.
Thanks for you reply. I understood ADC to I2S line setting.
How should they set it to bypass the effector(they want to process the data by external DSP, so internal effects are not necessary)?
And could you also tell me how to adapt I2Sin to DAC setting?
The digital effects are disabled and bypassed by default. Register 12, bits D3-D0 on page 0 control the digital effects filters.
Like Valerie mentioned above, the device is set to I2S communication by default. This is true for both ADC and DAC communication.

Thanks for your supplement. It makes sense for me!
