DESENSTHR<3:0>: Desensitization Threshold Field bits
This field defines an absolute level on the RSSI signal to activate receive signal processor if PSAV = 1.
Unit is: 4 dB/LSB. Unsigned encoding is used.
PSAVTHR<3:0>: Frame Detection Threshold Register Field bits
This field defines a relative (relative to the last 4 s RSSI value) threshold level on the RSSI signal to
activate receive signal processor if PSAV = 1.
Unit is 0.5 dB/LSB. Unsigned encoding is used.
