8.6.1
The digital audio interface formats (see Fig.5) can be
selected via pins SFOR1 and SFOR0 as shown in
Table 4.
For the digital audio interface holds that the
BCK frequency can be maximum 64 times WS frequency.
The WS signal must change at the negative edge of the
BCK signal for all digital audio formats.

This function is only available in audio mode. In that case,
pin DEEM/CLKOUT can be used to activate the digital
de-emphasis for 44.1 kHz as given in Table 5.
