M , L and R indicate inverted polarity of audio signal.
Dynamic compression can be used with external sources only. When dynamic compression is active, the radio quality detection of USN,
MOD and offset is limited to AF update tuning only. For dynamic compression the bits MOD[4:0] indicate the external source input
