Asynchronous Transparent Receive Mode
0894C–WIRE–11/08
Figure 3-1.
Set up by the MCU in receive mode, the AT86RF211S demodulates any data available on the antenna.
The data is given on the DATAMSG pin in real-time with no processing and no synchronization clock.
Figure 3-2.
Using a UART controller is a good solution in this case. NRZ or Manchester coding is possible, but is to
be held by the MCU itself.

AT86RF211S also acts like a "pipe":
data (collected by the antenna)
is available on pin DATAMSG
AT86RF211S
AT86RF211S acts like a "pipe"
(data is transmitted with NO
processing): automatic data
to frequency conversion.
