Abstract
A method for developing TDM data with embedded control data includes obtaining signal data and control data, formatting the signal data and the control data into a plurality of channels of a DIN signal, and transmitting the DIN signal on one line of a 3-bit TDM bus. A multichannel input device includes a control extractor receptive to the three-bit TDM bus and operative to extract CNTL data from the DIN data, a DAI receptive to the 3-bit TDM bus and the channel select input and operative to develop a SIGNAL data output, and a DAC block including a DAC, the DAC block being receptive to the SIGNAL data and the CNTL data.
