Table 8-5. Status CCA Algorithm
• Bit 6 – CCA_STATUS
CCA_STATUS register bit indicates the result of a CCA request. Each read access to
register 0x01 resets the CCA_STATUS bit.
Table 8-6. Status CCA Result
• Bit 5 – Reserved
• Bit [4:0] – TRX_STATUS
Refer to section 7.1.5.
Register 0x08 (PHY_CC_CCA)
The PHY_CC_CCA register contains register bits to initiate and control the CCA
measurement as well as to set the channel center frequency.
• Bit 7 – CCA_REQUEST
A manual CCA measurement is initiated with setting CCA_REQUEST = 1.
• Bit [6:5] – CCA_MODE
The CCA mode can be selected using register bits CCA_MODE.
Table 8-7. CCA Modes
• Bit [4:0] – CHANNEL
Refer to section 9.7.5.
