RSSI reading

The RSSI (Received Strength Signal Indicator) gives an indication for the received power level of the last
demodulated frame. It is available in S230 register. This level must be used with care due to dispersion between
components.The RSSI can also be added at the beginning of each incoming frame. The RSSI value is coded on
one byte. This byte codes the absolute value of the RSSI with a maximum at -70dBm.
