Step 1: The chip is set-up in sleep mode
using the 3-wire interface (SLE, SCK,
SDATA), then the microcontroller goes to sleep,
waiting for an interrupt on the wake-up pin

Data stored
Step 3: When a correct header is received (mandatory
and the address matches (if any), the data field
is then stored into AT86RF211S and the wake-up pin
is activated (to wake up the microcontroller).
The microcontroller then reads the data into one
of its registers, and begins a relevant procedure.
Note: The data field is optional: the chip can be simply
woken up with no dedicated data.
