5.2.6 Register Description
8168C-MCU Wireless-02/10
The TRX_END interrupt is always generated after completing a TX_ARET transaction.
After that, the return code can be read from subfield TRAC_STATUS (register 0x02,
TRX_STATE).
Several interrupts are automatically suppressed by the radio transceiver during
TX_ARET transaction. In contrast to section 6.6, the CCA algorithm (part of CSMA-CA)
does not generate interrupt IRQ_4 (CCA_ED_DONE). Furthermore, the interrupts
RX_START and AMI are not generated during the TX_ARET acknowledgment receive
process.
Register Summary
The following registers control the Extended Operating Mode.
Table 5-16. Extended Operating Mode Register Summary
Register 0x01 (TRX_STATUS):
The read-only register TRX_STATUS provides the current state of the radio transceiver.
A state change is initiated by writing a state transition command to register bits
TRX_CMD (register 0x02, TRX_STATE).
Table 5-17. Register 0x01 (TRX_STATUS)
• Bit 7:6 – CCA_DONE, CCA_STATUS
Refer to section 6.6.6; not updated in Extended Operating Mode.
