4.8Audio Interfaces
The audio interface circuit consists of:
Stereo/dual-mono audio codec
Dual analogue audio inputs
Dual analogue audio outputs
2 digital MEMS microphone inputs
A configurable PCM, I²S or SPDIF interface
Figure 9: Audio Interface
The interface for the digital audio bus shares the same pins as the PCM codec interface described. which means each of
the audio buses are mutually exclusive in their usage.
