This section summarizes all states to provide the basic functionality of the
Atmel AT86RF232, such as receiving and transmitting frames, the power-on sequence,
and sleep. The Basic Operating Mode is designed for IEEE 802.15.4 and general ISM
band 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 SLP_TR and /RST
pins. A successful state change can be verified by reading the radio transceiver status
from register bits TRX_STATUS (register 0x01, TRX_STATUS).
