IFMT
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 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.
