Table 6-31. CCA Algorithm Status
• Bit 6 – CCA_STATUS
After a CCA request is completed, the result of the CCA measurement is available in
register bit CCA_STATUS. Note that register bit CCA_STATUS is cleared in response
to a CCA_REQUEST.
Table 6-32. CCA Status Result
• Bit 5 – Reserved
• Bit 4:0 – TRX_STATUS
Register 0x08 (PHY_CC_CCA):
This register is provided to initiate and control a CCA measurement.
Table 6-33. Register 0x08 (PHY_CC_CCA)
• Bit 7 – CCA_REQUEST
A manual CCA measurement is initiated by setting CCA_REQUEST = 1. The register
bit
CCA_REQUEST = 1.
• Bit 6:5 – CCA_MODE
The CCA mode can be selected using register bits CCA_MODE.
Table 6-34. CCA Mode
Refer to sections 5.1.5 and 5.2.6.
