I2S Bus with both DAC and ADC as separate devices?

[StudentSA]

Good Day,

If an embedded system has one I2S bus with pins CLK, WS, SDO and SDI. Is it possible to connect two I2S IC devices? One being a DAC and one being an ADC? Where they share CLK, WS but the ADC will wired to SDI and DAC to SDO.

I have a device that uses a PCM5102 DAC and only the CLK,WS,SDO pins and I would now like to add a PCM1860 ADC using the CLK,WS and SDI pins.

I would start by looking in the datasheet of the microcontroller if it can support I2S receive and transmit at the same time. I doubt it will, because one way the clock is an input and the other way it is an output.
