audio data bus to minimize board routing area. PCM6xx0 supports a control bus using the I2C interface and an audio serial bus using a time-division multiplexed (TDM), Inter-IC Sound (I2S), or Left-justified (LJ) interface. Figure 1 shows a diagram of four PCM6xx0 devices sharing the control and audio data buses. Figure 1.

the former case, each TDM source shares a common data bus. The source must be configured to drive the bus only during its appropriate channel, and tri-state its driver while the other devices are driving the other channels. There is no standard for TDM interfaces, such as the Philips standard for I2S. This means that many ICs have their own
Multiple TLV320ADCx140 Devices With Shared TDM …

3 Sharing the Audio Bus TLV320ADCx140 devices send the digitized audio data through a Time Division Multiplexed (TDM) audio bus. A set of channel transfers starts at the rising edge of FSYNC with the first slot of data (slot 0), followed by the remaining data slots in increasing order (slot1, slot2, and so forth). A slot contains the

A2B Audio Bus | Analog Devices
https://www.analog.com/en/applications/technology/a2b-audio-bus.html
A 2 B is a high bandwidth, bidirectional, digital audio bus. A 2 B is capable of transporting I 2 S/TDM/PDM data and I 2 C control information, along with clock and power, using a single, 2-wire UTP cable over distances up to 15 m between nodes and 40 m over the entire daisy chain.
TDM Bus - Wikipedia
https://en.wikipedia.org/wiki/TDM_Bus
A TDM bus is one application of the principle of Time-Division Multiplexing . In a TDM Bus, data or information arriving from an input line is put onto specific timeslots on a high-speed bus, where a recipient would listen to the bus and pick out only the signals for a certain timeslot.
TDM for 16 audio channels. What's the best way? - Q&A ...

So you cannot send only one channel on an I2S signal. In TDM mode you would have all four on the bus so treat them however you like. Yes, you can daisy-chain two of these codecs to give you 8 ADC channels and 16 DAC channels. Then use another pair for the other 8 ADCs and 16 DACs. Now I would recommend that you operate the part in TDM 8 mode.

https://www.nxp.com/docs/en/application-note/AN12202.pdf
The audio bus (either for I2S, Codec/DSP modes, TDM, etc.) was designed to minimize the number of pins required and to keep wiring simple. A 3-line serial bus is used consisting of one serial data line, one channel/word selection and one clock line.
