Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
bit 3-0
BO<3:0>: Beacon Order bits (macBeaconOrder)⁽¹⁾
Specifies how often the coordinator will transmit a beacon.⁽²⁾
1111 = The coordinator will not transmit a beacon and the Superframe Order (SO) parameter value is
ignored (default)
1110 = 14
•

•
0000 = 0
SO<3:0>: Superframe Order bits (macSuperframeOrder)⁽¹⁾
Specifies the length of the active portion of the superframe, including the beacon frame.⁽²⁾
1111 = The superframe will not be active following the beacon (i.e., no active portion in the superframe
(default))
1110 = 14

0000 = 0
Note 1:
2:
Refer to IEEE 802.15.4™-2003 Standard, Section 7.5.1.1 “Superframe Structure”.
PANs that wish to use the superframe structure shall set macBeaconOrder to a value between 0 and 14
and macSuperframeOrder to a value between 0 and the value of macBeaconOrder
(i.e., 0 ≤ SO ≤ BO ≤ 14).
