DMic0 mono select: 0 = stereo operation, 1 = mono operation (left channel du-
plicated to the right channel).
3:2
Selects what phase of the DMic clock the data should be latched:
0h = left data rising edge/right data falling edge
1h = left data center of high/right data center of low
2h = left data falling edge/right data rising edge
3h = left data center of low/right data center of high
1:0
Selects the DMic clock rate:
0h = 4.704MHz
1h = 3.528MHz
2h = 2.352MHz
3h = 1.176MHz.
