The processing node is the high-pass filter (HPF). The processing state
is controlled as follows:
00h = Processing Off: HPF disabled
01h = Processing On: HPF enabled
02h = Processing Off: HPF disabled (benign not supported)
03h-7Fh = Reserved
80h-FFh = Vendor Specific – not used

Stream
RW
0h
Stream ID used by this widget. Note that Stream ID = 0h is used to
indicate an unused stream, and converters will not transfer/receive link
data for streams with an ID of 0h.
For multi-channel capture on MIC1 and MIC2, the Stream value should be
the same for both.
[3:0]
Channel
RW
0h
Lowest channel number used by this widget.
Note: When MIC1 and MIC2 are setup for multi-channel capture, only a
setting of 0h and 2h are applicable. However, the values are mutually
exclusive, in that if Channel has been set to 0h for the MIC1 node, it must
be set to 2h for the MIC2 node. Both nodes should have Channel set to 0h
