Trigger the STXON and STXONCCA strobes from GPIO pins. This gives the microcontroller very
accurate control of the timing of the outgoing frame.
Use a timer in the microcontroller to capture the timing of the SFD exception. This gives the
microcontroller exact knowledge of when the frame was transmitted.
Note that there is no requirement to have the complete frame in the TXFIFO before starting a
transmission. Bytes may be added to the TX FIFO during transmission.
It is possible to make CC2520 transmit non-IEEE 802.15.4 compliant frames by setting
MDMTEST1.MODULATION_MODE=’1’.
