CC2420
SFLUSHRX command strobe should be
issued twice to ensure that the
SFD
pin
goes back to its idle state.
For security enabled frames, the MAC
layer must read the source address of the
received frame before it can decide which
key to use to decrypt or authenticate. This
data must therefore not be overwritten
even if it has been read out of the RXFIFO
by
the
microcontroller.
SECCTRL0.RXFIFO_PROTECTION
control
bit is set,
CC2420
also protects the frame
header of security enabled frames until
decryption has been performed. If no MAC
security is used or if it is implemented
outside the
CC2420
, this bit may be cleared
to achieve optimal use of the RXFIFO.
