The RX ATTENUATION register sets the receiver attenuation level. If the
return signal is so strong that it saturates the receiver front end, set Max
power is achieved when this register is set at 0x3F. Each numeric value
below this level corresponds to an 0.5 dB attenuation from the max.
Examples of some typical settings are shown below.
