| 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. |
