Register 0x09 (CCA_THRES)
This register contains the threshold level for CCA-ED measurement.
• Bit [7:4] – Reserved
• Bit [3:0] – CCA_ED_THRES
The register bits CCA_ED_THRES define the threshold value of the CCA-ED
measurement. A cannel is indicated as busy when the received signal power is above
RSSI_BASE_VAL + 2 • CCA_ED_THRES [dBm].
