DMIC4L_

Control

10:8

IN4_OSR [2:0]

101

Input Path 4 DMIC Oversample Rate

Controls the DMIC4 sample rate as below:

000 = Reserved

001 = Reserved

010 = 384kHz

011 = 768kHz

100 = 1.536MHz

101 = 3.072MHz

110 = 6.144MHz

111 = Reserved

When IN4_OSR=010 or 011, then the

maximum Input Path sample rate (all input

paths) is 48kHz or 96kHz respectively.

If Input Path 4 DMIC is selected as a

source for the Rx ANC function, the

IN4_OSR field must be set to 101.

Input Path 5 DMIC Oversample Rate

Controls the DMIC5 sample rate as below:

000 = Reserved

001 = Reserved

010 = 384kHz

011 = 768kHz

100 = 1.536MHz

101 = 3.072MHz
