Register 0x01 (TRX_STATUS)
The TRX_STATUS register signals the current state of the radio transceiver as well as
the status of the CCA measurement. Note, a read access to the register clears bits
CCA_DONE and CCA_STATUS. This register is also used for Basic Operating Mode,
refer to section 7.1.
• Bit 7 – CCA_DONE
Refer to section 8.6.
