NDTHRES: FSK Noise Detector Threshold
See application notes “How to choose an Application specific Signal Detection
Threshold for TDA523x based ASK Mode Applications” and “How to Choose an
Application Specific Signal- and Noise-Detection Threshold for TDA523x based FSK
Mode Applications” for specific procedure to determine this threshold by application.
