9.4.2.3.3 Configuration of non IEEE 802.15.4 Compliant Scenarios
52
ATmega128RFA1
Second level of filtering according to IEEE 802.15.4-2006, section 7.5.6.2, is applied to
a received frame if the radio transceiver is in promiscuous mode. However, a
TRX24_RX_END interrupt is issued even if the FCS is invalid. Thus it is necessary to
read bit RX_CRC_VALID of register PHY_RSSI after the TRX24_RX_END interrupt in
order to verify the reception of a frame with a valid FCS.
If a device, operating in promiscuous mode, receives a frame with a valid FCS which in
addition passed the third level filtering according to IEEE 802.15.4-2006, section
7.5.6.2, an acknowledgement frame would be transmitted. According to the definition of
the promiscuous mode a received frame shall not be acknowledged even if it is
requested. Thus bit AACK_DIS_ACK of register CSMA_SEED_1 has to be set to 1.
In all receive modes a TRX24_AMI interrupt is issued, when the received frame
matches the node’s address according to the filter rules described in section
Filtering" on
Alternatively, in RX_ON state of the Basic Operating Mode when a valid PHR is
detected a TRX24_RX_START interrupt is generated and the frame is received. The
end of the frame reception is signalized with a TRX24_RX_END interrupt. At the same
time the bit RX_CRC_VALID of register PHY_RSSI is updated with the result of the
FCS check (see
order to dismiss corrupted frames according to the definition of the promiscuous mode.
Sniffer
Table 9-9 below
RX_AACK configuration bits should be set to their reset values (see
49). All frames received are indicated by a TRX24_RX_START and TRX24_RX_END
interrupt. Bit RX_CRC_VALID of register PHY_RSSI is updated after frame reception
with the result of the FCS check (see
needs to be checked in order to dismiss corrupted frames.
