5.2.3.3 Configuration of Non IEEE Compliant Scenarios
8168C-MCU Wireless-02/10
Table 5-11. Configuration of Promiscuous Mode
To signal the availability of frame data, an IRQ_3 (TRX_END) is issued, even if the FCS
is invalid. Thus, it is necessary to read register bit RX_CRC_VALID (register 0x06,
PHY_RSSI) after IRQ_3 (TRX_END) in order to verify the reception of a frame with a
valid FCS. Alternatively, bit 7 of byte RX_STATUS can be evaluated, refer to section
4.3.2.
If a device, operating in promiscuous mode, received a frame with a valid FCS that
furthermore passed the third level of filtering (according to IEEE 802.15.4-2006, section
7.5.6.2), an acknowledgement (ACK) frame would be transmitted. But, according to the
definition of the promiscuous mode, a received frame shall not be acknowledged, even
if requested. Thus, register bit AACK_DIS_ACK (register 0x2E, CSMA_SEED_1) must
be set to 1 to disable ACK generation.
In all receive modes, interrupt IRQ_5 (AMI) is issued if the received frame matches the
node’s address according to the filter rules described in section 6.2.
Promiscuous mode could also be implemented using state RX_ON (Basic Operating
Mode), refer to section 5.1. However, the RX_AACK transaction additionally enables
extended functionality like automatic acknowledgement and non-destructive frame
filtering.
Reserved Frame Types
In RX_AACK mode, frames with reserved frame types (refer to section 6.1.2.2, Table 6-
2) can also be handled. This might be required when implementing proprietary, non-
standard compliant protocols. The reception of reserved frame types is an extension of
the AT86RF212 Frame Filter, see section 6.2. Received frames are either handled like
data frames, or may be allowed to completely bypass the Frame Filter. The flow chart in
Figure 5-9 shows the corresponding state machine.
In addition to Table 5-9 or Table 5-10, the following Table 5-12 shows RX_AACK
configuration registers required to setup a node to receive reserved frame types.
