DATA BYTE
Setting of programmable counter of synthesizer PLL. Lower byte of PLL divider
word.
FM audio mute. If MUTE = 0, then FM audio not muted. If MUTE = 1, then FM audio
muted; writing to programmable divider enabled.
Setting of antenna digital auto alignment.
IF measuring time. If IFMT = 0, then IF measuring time is 20 ms. If IFMT = 1, then
IF measuring time is 2 ms.
Reference frequency for synthesizer. These 3 bits determine the reference
frequency, see Table 12.
IF counter prescaler ratio. If IFPR = 0, then IF prescaler ratio is 100. If IFPR = 1, then
IF prescaler ratio is 10.
Band switch. These 2 bits select in FM mode band and local or distant, see Table 13;
in AM mode band and AM stereo, see Table 14.
AM or FM switch. If AMFM = 0, then FM mode. If AMFM = 1, then AM mode
