7.2.3 Extended Operating Mode Description
7.2.3.1 RX_AACK_ON – Receive with Automatic ACK
5131E-MCU Wireless-02/09
In the RX_AACK_ON state, the radio transceiver listens for incoming frames. After
detecting a frame start (SFD), the radio transceiver state changes to BUSY_RX_AACK
(register 0x01) and the TRAC_STATUS bits (register 0x02) are set to INVALID. The
AT86RF230 starts to parse the MAC header (MHR) and a filtering procedure as
described in IEEE 802.15.4-2003 section 7.5.6.2. (third level filter rules) is applied
accordingly. It accepts only frames that satisfy all of the following requirements (quote
from IEEE 802.15.4 2003):
• The frame type subfield of the frame control field shall not contain an illegal frame
• If the frame type indicates that the frame is a beacon frame, the source PAN
• If a destination PAN identifier is included in the frame, it shall match macPANId or
• If a short destination address is included in the frame, it shall match either
• If only source addressing fields are included in a data or MAC command frame, the
The AT86RF230 requires to satisfy two additional rules:
• The frame type indicates that the frame is not an ACK frame (refer to Table 8-1)
• At least one address field must be present (refer to Table 8-2)
A frame is also discarded if the FCS is invalid. Otherwise, the TRX_END interrupt is
issued and the register bits TRAC_STATUS are set to SUCCESS after the reception of
the frame was completed. The microcontroller can then upload the frame.
The AT86RF230 detects whether an ACK frame needs to be sent. In that case, the
radio transceiver automatically generates an ACK frame which is transmitted 12 symbol
periods after the end of the received frame. If the frame that needs to be acknowledged
is a valid MAC command data request frame, the content of register bit AACK_SET_PD
in register 0x2E (CSMA_SEED_1) is copied to the frame pending subfield of the ACK
and the frame sequence number is copied likewise. During these operations the radio
transceiver remains in BUSY_RX_AACK state.
After the completion of the RX_AACK transaction the radio transceiver reenters the
state RX_AACK_ON.
The flow diagram of the RX_AACK algorithm is shown in Figure 7-6.
The timing of an RX_AACK transaction is shown in Figure 7-7. It shows a reception of a
data frame of length 10 with the ACK request bit set to one. A state change to
BUSY_RX_AACK is performed after SFD detection. The completion of the frame
reception is indicated by a TRX_END interrupt. The ACK frame is transmitted after a
wait period of 12 symbols (192 µs).

identifier shall match macPANId unless macPANId is equal to 0xFFFF, in which
case the beacon frame shall be accepted regardless of the source PAN identifier.
shall be the broadcast PAN identifier (0xFFFF).
macShortAddress or the broadcast address (0xFFFF). Otherwise, if an extended
destination address is included in the frame, it shall match an ExtendedAddress.
frame shall be accepted only if the device is a PAN coordinator and the source PAN
identifier matches macPANId. Any frames rejected by these rules are discarded.
