CCA_STATUS
Register 0x01 (TRX_STATUS):
Two register bits of register 0x01 (TRX_STATUS) signal the status of the CCA measurement.
• Bit 7 - CCA_DONE
This register indicates if a CCA request is completed. This is also indicated by an interrupt
IRQ_4 (CCA_ED_DONE). Note, register bit CCA_DONE is cleared in response to a
CCA_REQUEST.
Table 8-10.
• Bit 6 - CCA_STATUS
After a CCA request is completed the result of the CCA measurement is available in register bit
CCA_STATUS. Note, register bit CCA_STATUS is cleared in response to a CCA_REQUEST.

Register 0x08 (PHY_CC_CCA):
This register is provided to initiate and control a CCA measurement.
• Bit 7 - CCA_REQUEST
A manual CCA measurement is initiated with setting CCA_REQUEST = 1. The end of the CCA
measurement is indicated by interrupt IRQ_4 (CCA_ED_DONE). Register bits CCA_DONE and
