7
Reserved
Reserved: Must be set to low
6
ASC-
When high, internal adaptation speed control is disabled.
When low, internal adaptation speed control is enabled.
5
NLP-
When high, the non-linear processor in the Sin/Sout path is disabled.
When low, the non-linear processor in the Sin/Sout path is enabled.
4
NJ-
When high, the noise filtering process is disabled in the NLP.
When low, the noise filtering process is enabled in the NLP.
3
HPF-
When high, the offset nulling filter is bypassed in the Sin/Sout path.
When low, the offset nulling filter in the Sin/Sout path is active and will
remove DC offset on the Rin input signal.
2
HCLR
When high, the H register in the adaptive filter is cleared.
When low, the H register is not cleared
1
ADAPT-
When high, echo canceller adaptation is disabled.
When low, the echo canceller adapts to the echo path characteristics.
0
ECBY
When high, the echo estimate from the adaptive filter is not subtracted from
the Send path.
When low, the echo estimate is subtracted from the Send path.
