• Bit 4 – AACK_DIS_ACK
If this bit is set, no acknowledgment frames are transmitted in RX_AACK Extended
Operating Mode, even if requested.
• Bit 3 – AACK_I_AM_COORD
This register bit has to be set if the node is a PAN coordinator. It is used for frame
filtering in RX_AACK mode.
If I_AM_COORD = 1 and if only source addressing fields are included in a data or MAC
command frame, the frame shall be accepted only if the device is the PAN coordinator
and the source PAN identifier matches macPANId. For details, refer to IEEE 802.15.4-
2006, section 7.5.6.2 (third-level filter rule 6).
• Bit 2:0 – CSMA_SEED
These register bits are the higher 3 bit of the CSMA_SEED, i.e. bits [10:8]. The lower
part is in register 0x2D (CSMA_SEED_0), see register CSMA_SEED_0 for details.
Register 0x2F (CSMA_BE):
Table 5-29. Register 0x2F (CSMA_BE)
• Bit 7:4 – MAX_BE
Register bits MAX_BE define the maximum value of the backoff exponent in the CSMA-
CA algorithm. It equals macMaxBE; refer to section 7.5.1.4 of [2]. Valid values are
[4’d8, 4’d7, … , 4’d3].
• Bit 3:0 – MIN_BE
Register bits MIN_BE define the minimum value of the backoff exponent in the
CSMA-CA algorithm. It equals to macMinBE; refer to section 7.5.1.4 of [2]. Valid values
are [MAX_BE, (MAX_BE – 1), … , 4’d0].
Note
• If MIN_BE = 0 and MAX_BE = 0, the CCA backoff period is always set to 0.
