This register sets the threshold level for the Energy Detection (ED) of the Clear Channel
Assessment (CCA).
Bit 7:4 – CCA_CS_THRES3:0 - CS Threshold Level for CCA Measurement
These bits are reserved for internal use.
Bit 3:0 – CCA_ED_THRES3:0 - ED Threshold Level for CCA Measurement
These bits define the received power threshold of the Energy above threshold
algorithm. The threshold is calculated by RSSI_BASE_VAL + 2CCA_ED_THRES
[dBm]. Any received power above this level is interpreted as a busy channel.

The register controls the sensitivity of the Antenna Diversity Mode. Note that in High
Data Rate modes the ACR module will always be disabled.
Bit 7:4 – Resx7:4 - Reserved
Bit 3:0 – PDT_THRES3:0 - Receiver Sensitivity Control
These register bits control the sensitivity of the receiver correlation unit. If the Antenna
Diversity algorithm is enabled the value shall be set to PDT_THRES = 3. Otherwise it
shall be set back to the reset value. Values not listed in the following table are reserved.
