Reference divide register (1 to 2047) sets the internal reference frequency.
Internal Reference Frequency = Reference Oscillator Frequency / Reference divide register
e.g.
12MHz reference crystal, Ref divider of 240, gives 50kHz internal reference frequency.
PDR select sets the IF and BWdm.
FM Demodulator bandwidth, BWdm = (Receiver LO) / (580 x PDR)
IF frequency,
Fif = (Receiver LO) / (544 x PDR)
e.g.
915MHz frequency, PDR of 12, gives 131kHz demodulator bandwidth and 140kHz IF.
For the above example,
Programming word = 0000000 010 00011110000 00
