48 When using two MAX9892X in a system it is possible to create ADC data
49 that will overflow the frame size. When enabled, the Digital Audio
50 Interleave mode provides a means to output VMON and IMON data from two
51 devices on a single DOUT line when running smaller frames sizes such as
52 32 BCLKS per LRCLK or 48 BCLKS per LRCLK.
