CARRIER DETECTOR THRESHOLD SELECTION
The carrier detector indicates if a carrier signal is present on the selected channel. The nominal value and tolerance of
the carrier detector threshold is given in the carrier detector specification section. If a different carrier detector threshold
value is desired, it can be selected via the microcontroller interface.
If it is required to scale the carrier detector range, an external resistor should be connected between pin RSSI and
ground. The carrier detector threshold step 19 (10011) corresponds to a typical level on pin RSSI of 0.86 V DC.
