Recommended RF Settings
This section contains a summary of the register settings that must be updated from their default value to have
optimal performance. The following settings should be set for both RX and TX. Although not all settings are
necessary for both RX and TX, it is recommended for simplicity (allowing one set of settings to be written at the
initialization of the code).
