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.
