[Tinyos-help] CC2420 MAC Implementation

Hi all,

I have a problem with cc2420 mac implementation. TinyOS FAQ(
http://www.tinyos.net/faq.html) says: The CC2420 radio stack does not
support the full IEEE 802.15.4 standard; instead it provided B-MAC
primitives and sends 802.15.4-compliant packets, but does not implement the
802.15.4 MAC protocol.

CC2420 provided B-MAC primitives, and where is the primitives? Is it in
/opt/tinyos-2.1.0/tos/chips/cc2420/csma or
/opt/tinyos-2.1.0/tos/chips/cc2420/lpl? Is there examples that i can verify
the B-MAC?

Any help is highly appreciated. Thank you for your help!

Regards,
Lizhao
