The device will accept audio samples in several digital interface formats. The desired format is selected
via the DIF0, DIF1 and DIF2 bits in the Mode Control register (see section 6.2.2). For an illustration of the
required relationship between LRCK, SCLK and SDATA, see Figures 17 through 19.

The device will enter the External Serial Clock Mode whenever 16 low to high transitions are de-
tected on the SCLK pin during any phase of the LRCK period. The device will revert to Internal
Serial Clock Mode if no low to high transitions are detected on the SCLK pin for 2 consecutive pe-
riods of LRCK.
