5.1.5 Register Description
40
AT86RF212
Register 0x01 (TRX_STATUS):
A read access to TRX_STATUS register signals the current radio transceiver state. A
state change is initiated by writing a state transition command to register bits
TRX_CMD (register 0x02, TRX_STATE). Alternatively, a state transition can be initiated
by the rising edge of pin 11 (SLP_TR) in the appropriate state. This register is used for
Basic and Extended Operating Mode, refer to section 5.2.
Table 5-3. Register 0x01 (TRX_STATUS)
• Bit 7:6 – CCA_DONE, CCA_STATUS
Refer to section 6.6.6.
• 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. Do not try to initiate a further state change
while the radio transceiver is in STATE_TRANSITION_IN_PROGRESS.
