AMFM
IF counter prescaler ratio. If IFPR = 0, then IF prescaler ratio is 40. 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 14; in
AM mode band and AM stereo, see Table 15.
AM or FM switch. If AMFM = 0, then FM mode. If AMFM = 1, then AM mode.
