AIF2DAC_DIV

[2:0]

000

Selects the AIF2 input path sample rate relative to the AIF2

output path sample rate.

This field should only be changed from default in modes

where the AIF2 input path sample rate is slower than the

AIF2 output path sample rate.

000 = Divide by 1

001 = Divide by 1.5

010 = Divide by 2
