The device will accept audio samples in several digital interface formats as illustrated in Tables 5 and 8.
The desired format is selected via the M0 and M1 pins for stand alone mode, and through the DIF2:0 bits
in the control port. For an illustration of the required relationship between the Left/Right Clock, Serial
Clock and Serial Audio Data, see Figures 4-6.
