preamble length in protocol

   I have a question on b-mac protocol.
   In b-mac the preamble length must match the check interval, but the preamble lenght controled by cc2420
register MDMCTRL0.PREAMBL is only 4 bits

 (#define CC2420_MDMCTRL0_PREAMBL      0   // 4 bits (0..3): Preamble length)
I think it can't match the check interval which can reach as much as 1600ms at best.

I'm really confused. Can you give me some help!

Thank you!

                        Happy Spring Festival!
