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