50.1 Overview
The I2S controller supports I2S audio, with up to 8-channels.
The additional Audio codex support includes TDM allowing multiple channels of data to be transmitted on a single data line. The TDM interface is similar to the 2 channel serial audio interface I2S, with the exception that more channels are transmitted within a sample frame or sample period. As with the I2S interface the TDM interface is comprised of two control clocks, a serial audio left/right clk ( LRCK) and serial audio bit clk (SCLK) and the serial audio data line (SDATA).
Additional TDM support for a wide variety of serial data formats. The TDM format is typically used to transfer data to or from a DSP to a MCU. The TDM format consist of three components clock, data, and frame sync (I2S could be considered a subset of TDM).
