HDA Defined Processing State: Writes to these
bits set the Widget to the processing state as
described below:
’00’h; Processing Off.
’01’h; Processing On.
’02’h; Processing Benign. Benign state is not
supported. Will be treated as “Processing Off”.
’03’h - ‘7F’h; - Reserved
6.15.4 Coefficient Index
The Coefficient Index is a zero-based index into the processing coefficient list which will be either read
or written using the Processing Coefficient control. When the coefficient has been read or written to, the
Coefficient Index will automatically increment by one so that the next Set Processing Coefficient verb will
load the coefficient into the next slot. The auto-increment feature can be disabled by setting the Disable
Coefficient Index Auto-Increment bit in the DAC Configuration (CIR = 0003h) register. The auto-increment
feature will “wrap around” at a Coefficient Index value of 04h, that is an index of 04h will be auto-incre-
mented to an index of 00h. If Coefficient Index is set to be greater than the number of “slots” in the pro-
cessing coefficient list, unpredictable behavior will result if an attempt is made to Get or Set the processing
coefficient.
