2.3 REGISTER R2
2.3.1 R[5:0] -- R Counter Value
These bits determine the phase detector frequency. The OSCin frequency is divided by this R counter value. In single-ended
mode, values of 1-63 are allowed. In differential mode, only 1,2,4,8,16, and 32 are allowed.

2.3.2 DEN[21:12] and DEN[11:0]-- Fractional Denominator
These bits determine the fractional denominator. Note that the MSB bits for this word are in register R3. If the FDM bit is set to
0, DEN[21:12] are ignored.
