command to the TRX_CMD bits of register TRX_STATE. The register is not accessible
in SLEEP state.
• Bit 7 – CCA_DONE - CCA Algorithm Status
This bit indicates if a CCA request is completed. This is also indicated by a
TRX24_CCA_ED_DONE interrupt. Note that register bit CCA_DONE is cleared in
response to a CCA_REQUEST.
Table 9-30 CCA_DONE Register Bits
• Bit 6 – CCA_STATUS - CCA Status Result
The result of the CCA measurement is available in register bit CCA_STATUS after a
CCA request is completed. Note that register bit CCA_STATUS is cleared in response
to a CCA_REQUEST.
Table 9-31 CCA_STATUS Register Bits
• Bit 5 – TST_STATUS - Test mode status
This bit is reserved for internal use. It indicates the status of the test mode.
Table 9-32 TST_STATUS Register Bits
• Bit 4:0 – TRX_STATUS4:0 - Transceiver Main Status
The register bits TRX_STATUS signal the current radio transceiver status. Do not try to
initiate
STATE_TRANSITION_IN_PROGRESS state. Values not listed in the following table
are reserved.
