Wake-up Mode
AT86RF211S
Figure 1-3.
The chip is set-up in a special Rx mode called sleep mode. The chip wakes up periodi-
cally thanks to its internal timer (in a stand-alone procedure, the microcontroller is in
power-down mode), and waits for an expected message defined previously. If no correct
sequence is received, the periodic scan continues.
If a correct message is detected, its data field is stored into the AT86RF211S (up to 32
bits) and an interrupt is generated on the WAKEUP pin.
Please refer to Figure 1-3 on page 6.
