23.5.1.1 IEEE 802.15.4 Radio Operation Command Structures
For all radio operation commands, the first 14 bytes shall be as defined in Table 23-8. The
CMD_IEEE_ABORT_BG command does not have any additional fields to those 14 bytes.
Table 23-56. IEEE 802.15.4 RX Command Structure
Bytes Field Name Type Description
Channel to tune to in the start of the operation
0: Use existing channel
11–26: Use as IEEE 802.15.4 channel, that is frequency is (2405 + 5 ×
14 channel W
(channel − 11)) MHz
60–207: Frequency is (2300 + channel) MHz
Others: reserved
15 rXConfig W Configuration bits for the receive queue entries, see Table 23-67 for details
16–19 pRxQ W Receive queue
20–23 pOutput W Pointer to result structure, see Table 23-66 (NULL: Do not store results)
24–25 frameFiltOpt R/W Frame filtering options, see Table 23-69 for details
26 frameTypes R/W Frame types to receive in frame filtering, see Table 23-70 for details
