AT86RF231
Notes:
1. In SLEEP state register not accessible.
2. Do not try to initiate a further state change while the radio transceiver is in
STATE_TRANSITION_IN_PROGRESS state.
Register 0x02 (TRX_STATE):
The AT86RF231 radio transceiver states are controlled via register TRX_STATE using register
bits TRX_CMD. The read-only register bits TRAC_STATUS indicate the status or result of an
Extended Operating Mode transaction.
A successful state transition shall be confirmed by reading register bits TRX_STATUS (register
0x01, TRX_STATUS).
Register bits TRX_CMD are used for Extended and Basic Operating Mode, refer to
“Basic Operating Mode” on page 33
.
• Bit [7:5] - TRAC_STATUS
The status of the RX_AACK and TX_ARET procedure is indicated by register bits
TRAC_STATUS. Details of the algorithm and a description of the status information are given in
Table 7-15.
