• Bit [7:5] – TRAC_STATUS
The status of the TX_ARET algorithm is indicated by register bits TRAC_STATUS.
Details of the algorithm and a description of the status information are given in section
7.2.3.2.
Table 7-8. State Control Register, Register Bits TRAC_STATUS TX_ARET
• Bit [4:0] – TRX_CMD
A write access to register bits TRX_CMD initiates a radio transceiver state transition
towards the new state.
Table 7-9. State Control Register, Register Bits TRX_CMD
Register 0x2C (XAH_CTRL)
The XAH_CTRL register controls the TX_ARET transaction in the Extended Operating
Mode of the radio transceiver.
