2. EMCK, ELRCK, EBICK and DAUX
In asynchronous mode, the audio data format of DAUX is selected by EDIF1-0 bits. The clock source of master clock
selects X’tal or EMCK by the MSEL bit. In parallel mode, this function is not supported.

Table 30. Audio data format in asynchronous mode
Default
In asynchronous mode, the frequecny of EMCK/X’tal selects 128fs, 256fs or 512fs. It is controlled by ECKS1-0 bit.
