47.1 Overview

The I^XS controller supports I^XS 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).
