Read/Write
Reset value
• Bit 7 – CCA_DONE
Refer to section 8.6.
• Bit 6 – CCA_STATUS
Refer to section 8.6.
• Bit 5 – Reserved
• Bit [4:0] – TRX_STATUS
The register bits TRX_STATUS signal the current radio transceiver status. If the
requested state transition is not completed yet, the TRX_STATUS returns
STATE_TRANSITION_IN_PROGRESS. State transition timings are defined in Table
7-1.
Table 7-3. Radio Transceiver Status, Register Bits TRX_STATUS
Register 0x02 (TRX_STATE)
The register TRX_STATE controls the radio transceiver states via register bits
TRX_CMD. The status and the result of a TX_ARET/RX_AACK transaction is indicated
by register bits TRAC_STATUS.
A successful state transition shall be confirmed by reading register bits TRX_STATUS
in register 0x01 (TRX_STATUS).
This register is used for Basic and Extended Operating Mode. The Extended Operating
Mode functionality is described in section 7.2.
