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.

Step 2: The chip wakes-up periodically,

waiting for an expected message

(stand-alone operation)

Step 1: The chip is set up in sleep mode

using the 3-wire interface (SLE, SCK,

SDATA), then Microcontroller goes to sleep,

waiting for an interrupt on WAKEUP pin
