Register 0x09 (CCA_THRES):
This register is relevant for the ED threshold when using LBT.
Table 6-37. Register 0x09 (CCA_THRES)
• Bit 7:4 – Reserved
• Bit 3:0 – CCA_ED_THRES
For CCA_MODE = 1, a busy channel is indicated if the measured received power is
above (RSSI_BASE_VAL + 2.07 ⋅ CCA_ED_THRES) [dBm]. CCA_MODE = 0 and 3 are
logically related to this result.
Register 0x17 (XAH_CTRL_1):
This register is relevant for enabling or disabling the LBT mode.
Table 6-38. Register 0x17 (XAH_CTRL_1)
• Bit 7 – Reserved
• Bit 6 – CSMA_LBT_MODE
If set to 0 (default), CSMA-CA algorithm is used during TX_ARET for clear channel
assessment. Otherwise, the LBT specific listening mode is applied.
• Bit 5:4 – AACK_FLTR_RES_FT, AACK_UPLD_RES_FT
Refer to section 5.2.6.
• Bit 3 – Reserved
• Bit 2:1 – AACK_ACK_TIME, AACK_PROM_MODE
Refer to sections 5.2.6 and 5.2.3.3.
• Bit 0 – Reserved
