DMic1 mono select: 0 = stereo operation,
1 = mono operation (left channel duplicated
to the right channel).
DMic0 mono select: 0 = stereo operation,

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
Selects the DMic clock rate:
0h = 4.704MHz; 1h = 3.528MHz;
2h = 2.352MHz; 3h = 1.176MHz.
