Bit 7 – CCA_DONE CCA_DONE
The CCA_DONE bit indicates if a CCA request is completed. This is also indicated by an interrupt IRQ_4 (CCA_ED_DONE). The register bit CCA_DONE is cleared in response to a CCA_REQUEST.
| Value | Description |
|---|---|
| 0x0 | CCA calculation not finished |
| 0x1 | CCA calculation finished |
Bit 6 – CCA_STATUS CCA_STATUS
After a CCA request is completed, the result of the CCA measurement is available in the CCA_STATUS bit. The register bit CCA_STATUS is cleared in response to a CCA_REQUEST.
| Value | Description |
|---|---|
| 0x0 | Channel indicated as busy |
| 0x1 | Channel indicated as idle |
Bits 4:0 – TRX_STATUS[4:0] TRX_STATUS
The register bits TRX_STATUS signal the current radio transceiver status.

- In SLEEP or DEEP_SLEEP state register not accessible.
- Extended Operating Mode only.
- Do not try to initiate a further state change while the radio transceiver is in STATE_TRANSITION_IN_PROGRESS state.
A read access to register bits TRX_STATUS reflects the current radio transceiver state. A state change is initiated by writing a state transition command to register bits TRX_CMD (register 0x02, TRX_STATE). Alternatively, some state transitions can be initiated by the rising edge of SLP_TR in the appropriate state.
These register bits are used for Basic and Extended Operating Mode.
If the requested state transition has not been completed, the TRX_STATUS returns STATE_TRANSITION_IN_PROGRESS value. Do not try to initiate a further state change while the radio transceiver is in STATE_TRANSITION_IN_PROGRESS state.
