DATA BYTE
This bit is not used and should be set to logic 0.
Reference frequency for synthesizer. These 3 bits determine the reference frequency,
see Table 12.
This bit is not used and should be set to logic 0.
Band switch. These 2 bits select the frequency in AM and FM mode, see Tables 13
and 14.
AM or FM switch. If AMFM = 0, then FM mode. If AMFM = 1, then AM mode.
