The value that is programmed here is interpreted as fraction of samples crossing signal threshold in given
time constant that is assumed to be programmed already. So, this macro should be given only after the
time constant setting macro is given.
This Fraction is interpreted as a 16 bit precision value with the value 2
16
corresponding to 100%.
In every time period, the attack detectors will trigger if the signal is above the programmed threshold for
the fraction of the time that is given here.
Similarly, the decay detectors will trigger if the signal is below the programmed threshold for the fraction of
the time that is given here.
