Header + Address
Step 3: If a correct header is received (mandatory)
and address matches (if any), the data field
is then stored into AT86RF211 and WAKEUP pin is
activated (to wake-up the Microcontroller).
The Microcontroller will then read the data into one
of its registers, and begin a relevant procedure.
Note: Data field is optional: the chip can be simply
woken-up with no dedicated data.
