TW
The parameter TW for a time t ([ms]) can be calculated by the following formula:
Value range: [0x00..0xFF] = [0ms..4080ms]
DS
The parameter DS for a decay rate R ([ms/dB]) can be calculated by the following
formula:
Value range: [0x00..0xFF] = [0.66ms/dB..678.3ms/dB]
Note: The value 0xFF for the parameter DS specifies an infinite decay rate. Therefore

h
the speakerphone will not return to the idle state in the absence of speech signals.
It will remain in the current state until a speech signal is detected and a state
change is necessary. This is also the reset and default value.
