Description:
After this processing, the OCFG stage is applied on
these channels. OCFG must be configured to 0 and
attenuation on all channels must be set to 10dB at-
tenuation.
The other values must not be used because low fre-
quency extraction must not be done when generating
pink noise.
Pink noise selection is made through the
STREAM-
SEL and
DECODSEL registers.
