47    description:
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.
