FspThr_S2 - Sat2 TDM Decoding FSP Invalid Threshold
Threshold of the FSP correlation determining an invalid FSP detection if not exceeded.
MetricCtrl_S2 - Satellite One TDM Decoding QPSK Metric Generation Data Control
Enables swap of data I- and Q-component and QPSK-map inversion if the corresponding bit is set. Determines
the threshold of the Soft Decision Slicer and the applied data output format.
