Basic Operating Mode State Diagram (for timing refer to
This section summarizes all states to provide the basic functionality of the AT86RF231, such as
receiving and transmitting frames, the power up sequence and sleep. The Basic Operating
Mode is designed for IEEE 802.15.4 and ISM applications; the corresponding radio transceiver
states are shown in
The radio transceiver states are controlled either by writing commands to register bits
TRX_CMD (register 0x02, TRX_STATE), or directly by two signal pins: pin 11 (SLP_TR) and
