Functional Description of Register Bits
When high, the comfort noise level estimator actively rejects double-talk as being background
noise. When low, the noise level estimator makes no such distinction.
Selects which noise ramping scheme is used. See Table below.
When high, the comfort noise level estimator actively rejects uncancelled echo as being
background noise. When low, the noise level estimator makes no such distinction.
NLRun2
InjCtrl
NLRun1
RingClr
When high, the instability detector is activated. When low, the instability detector is disabled.
Reserved bit. Must always be set to one for normal operation.
When high, the current echo channel estimate will be cleared and the echo canceller will enter
fast convergence mode upon detection of a path change. When low, the echo canceller will keep
the current path estimate but revert to fast convergence mode upon detection of a path change.
Note: this bit is ignored if PathDet is low.
When high, the path change detector is activated. When low, the path change detector is
disabled.
When high, the Advanced NLP is selected. When low, the original NLP is selected.
