The threshold detector compares the modulus of the source input value (defined by Pr 12.03, Pr 12.23), converted to a percentage of its maximum
value, with the threshold level (Pr 12.04, Pr 12.24). If the value is greater or equal to the threshold plus half the hysteresis band (Pr 12.05, Pr 12.25)
the output becomes active, or if the value is less than the threshold minus half the hysteresis band the output becomes inactive. The output may be
inverted if required by setting the invert flag (Pr 12.06, Pr 12.26). The result is routed to the destination (defined by Pr 12.07, Pr 12.27).
