The macMinBE and macMaxCSMABackoff values are
set to the IEEE 802.15.4 Standard defaults. To change
their values:
• macMinBE – Program MACMINBE (TXMCR
• macMaxCSMABackoff – Program CSMABF
0x11<4:3>) bits to a value between 0 and 3 (the
default is 3).
(TXMCR 0x11<2:0>) bits to a value between 0
and 5 (the default is 4).
