IFMT
IF measuring time. If IFMT = 0, then IF measuring time is 20 ms. If IFMT = 1, then
IF measuring time is 2 ms.
6 to 4
RFS[2:0]
Reference frequency for synthesizer. These 3 bits determine the reference
frequency, see Table 12.
3
IFPR
IF counter prescaler ratio. If IFPR = 0, then IF prescaler ratio is 100. If IFPR = 1, then
IF prescaler ratio is 10.
2 and 1
BND[1:0]
Band switch. These 2 bits select in FM mode band and local or distant, see Table 13;
in AM mode band select and output of AM IF2 for AM stereo, see Table 14.
0
AMFM
AM or FM switch. If AMFM = 0, then FM mode. If AMFM = 1, then AM mode.
