8.4.10 Echo Reference

The TAS2764 has a dedicated mode to loop back the DSP output.

This feature allows user to do noise cancellation or echo correction algorithms.

A block diagram is presented in the figure below.

GUID-DECC8FDB-20AE-4B1D-A907-FD9D0A7EAE9C-low.gif Figure 8-11 Echo Reference Loopback

The echo reference can be enabled by configuring AUDIO_TX bit in TDM_CFG12 register. The slot length and the time slot can be selected using AUDIO_SLEN and AUDIO_SLOT bits in TDM_CFG12 register.
