3.2.3 TDM Receiver and Transmitter PPC3 Configuration

TDM panel includes all the configuration related to the I2S/TDM audio interface. There is a dedicated tab for Receiver (SDIN) and Transmitter (SDOUT). Default settings match with USB controller configuration, however these can be overridden similarly as explained for the previous section.

Receiver configuration can be used to modify the digital audio format in terms of Edge Polarity, Justification, Frame Start Polarity, Offset Bits, Word Length and Slot Length. In addition to that, the input data can be arranged from multiple slots or even select a couple slots to result in a mono-mix playback.

Transmitter configuration provides similar settings for SDOUT timing. Similarly, the output data slots can be arranged based on the application requirements; take into consideration that SDOUT slots are always considered as 8-bit, so for 16-bit data length 2 slots must be used, and for 32bit data length 4 slots areov required.
