SFD
A general timing example of an RX_AACK transaction is shown in Figure 5-11. In this
example, a data frame with an ACK request is received. The AT86RF212 changes to
state BUSY_RX_AACK after SFD detection. The completion of the frame reception is
indicated by a TRX_END interrupt. The interrupts IRQ_2 (TX_START) and IRQ_5 (AMI)
are disabled in this example. The ACK frame is automatically transmitted after
aTurnaroundTime (12 symbols), assuming default acknowledgment frame start timing.

Overview
The TX_ARET Extended Operating Mode supports the frame transmission process as
defined by IEEE 802.15.4-2006. It is invoked as described in section 5.2.1 by writing
TX_ARET_ON to register subfield TRX_CMD (register 0x02, TRX_STATE).
