Application of TDM on NRF5340

[mingjkl]

Our project uses nrf5340, and we hope to match it with two wm8904 audio chips. They communicate with each other using the I2S protocol. However, we noticed that two I2S buses are required for two wm8904 chips, while nrf5340 has only one I2S bus. How do I handle this?
The technical support of the wm8904 asked whether the nrf5340 supports the TDM protocol. I have not found the content of the TDM protocol in the NRF5340 specification. How can I use the TDM protocol on the NRF5340?

Hello,

There is no support for TDM, so you will need to fit audio data within the standard I2S interface of the nRF5340:

As you write, there is only one I2S interface of the nRF5340, I don't see any way to emulate a second I2S interface.
