Important Note:

The I²S interface is provided as a test interface and is only accessible when running the CSR8635 QFN in HCI-

only mode.

The digital audio interface supports the industry standard formats for I²S, left-justified or right-justified. The interface

shares the same pins as the PCM interface, which means each audio bus is mutually exclusive in its usage. Table

9.8 lists these alternative functions. Figure 9.20 shows the timing diagram.
