Generic TDM Interface 1.1 Channel Block Each channel block is comprised of the audio data word followed by a sufficient number of zero data bits to complete the N-bit channel block. The example shown in Figure 3 shows a 32 ...

channels of data are to be transferred on a single data line. A TDM data stream can carry as many as sixteen channels of data and has a data/clock configuration similar to that of I2S. Each channel of data uses a slot on the data bus that is 1/Nth the width of the frame, where N is the number of channels being transferred.

The mutes are separate. It is just in transmitting the data out. If you set it to I2S stereo format then the signals will go out on the I2S data as left and right channels but those are only names. 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.

The IPB-I2S-TDM core is a serial audio transceiver designed to input and output digital audio streams in TDM full duplex. The IPB-I2S-TDM core also supports the well-known stereo formats: I2S, Left-Justified or Right-Justified. The backend interface is supplied with a choice of AMBA-AXI, AMBA-AHB, AMBA-APB, Avalon-MM or a parallel interface ...

TDM for 6 audio channels - Q&A - Audio - EngineerZone
https://ez.analog.com/audio/f/q-a/166490/tdm-for-6-audio-channels
TDM for 6 audio channels. We are designing a consumer electronics product which needs multiple audio inputs to be fed together to and handled by a single processor. We expect maximum 6 stereo signals to be handled. AD1938 seems to be a suitable option to mux these signals and feed to our processor.

You only have one data in your TDM signal. So only left channel have output while right channel have no audio input. Like I said before, we must need at least two TDM data to achieve both audio output for left and right. Pls count the number of bclk carefully. Below TDM format wave can be your reference. Leon
