The commandanswer is :
a) If TD_W_ADDR= 0 :
- FirstByte is the Node Number of the Signalconnectedto BiquadraticFilter input.
- SecondByte is the Node Number of the Signal connectedto the Energy estimator input.
b) if TD_W_ADDR = 1 :
- FirstByte is the Node Number of the Signalconnectedto ComparatorNegative input.
- SecondByteis theNode Numberof theSignalconnectedto theComparatorPositiveinput.
For secondarytone detectorTD_W_ADDR is not defined.
- First byte is 00 if relativecomparisonis not mandatory,
First byte is 01 if relativecomparison is mandatory.
- Second byte is for the configurationof the secondarytone detector:
C0 configuration1+1 of secondarytone detectors,
E0 configuration1+1+2,
F0 configuration1+1+1.
