[Tinyos Core WG] Fwd: CC2420 Security Support Documentation

[JeongGil (John) Ko]

Hi Miklos!
The CC2420SecurityMode is only active for the next AMSend.send command. You
can set different security options for different messages on a per message
basis. The security header is attached when an AMSend is called through a
SecAMSend interface.

Thanks.

-John
