Note: Of course, ADC/DAC/SoC are not the only kind of devices you can find in a I2S system. But for the other kind of devices, the same rationale can often be applied. For example: S/PDIF transmitters are often slave-only, while receivers can usually act as both master or slave.

The I2S bus interface of the I2S Audio Interface is a set of unidirectional signals that connect to chip I/O pads to form the off-chip I2S bus signals: serial clock (I2SCLK), word select (I2SWS), serial data in (I2SSDI), and serial data out (I2SSDO). To reduce chip-level pin count, the I2S bus interface signals can be shared with other on-chip

Hi _Lina, I suggest to take a look of this document: Audio Serial Interface Configurations for Audio Codecs.It could help you to understand about the I2S behavior as a master and as a slave. Regarding your question about the communication between slaves, when a device is working as slave, the BCLK and WCLK are placed as inputs.

system master controlling digital audio data-flow between the various ICs. Transmitters then, have to generate data under the control of an external clock, and so act as a slave. Figure 1 illustrates some simple system configurations and the basic interface timing. Note that the system master can be combined with

Each I2S interface can support upto 16 channels in TDM mode (ie. dsp-a/b modes). However, it is also possible to do what you are asking using the ADX module (audio demultiplexer). The ADX can take a input stream of N channels (where N is between 1 and 16) and split into up to 4 output streams of M channels (where M is between 1 and 16).
I²S - Wikipedia
https://en.wikipedia.org/wiki/I%C2%B2S
I²S, is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device. The I²S bus separates clock and serial data signals, resulting in simpler receivers than those required for asynchronous communications systems that need to recover the clock from …

The master can be configured for either 16 or 24 bit audio, which results in one of the following two signal sets: 16 bit stereo: MCLK: 12.288 MHz (fs * 256) LRCLK: 48 kHz (fs) BCLK: 1.536 MHz (fs * 32) SDATA: Slave ADAU transmits data for the left channel, but nothing for the right channel; 24 bit stereo: MCLK: 12.288 MHz (fs * 256) LRCLK: 48 kHz (fs)
