VCO Selection
With bit D12
Gaussian Filter On/off
With bit D0
GF is used only in TX mode.
D0
GFCS Adjustment
With bits D7 - D9
Only in TX mode effective for setting the frequency deviation of the modulation.
GFCS (Gaussian Filter Settings)
D9
D8
CPCS Adjustment
With bits D1 - D2
Used to adjust the charge pump current. This can be used to compensate the change of
the tuning sensitivity over frequency and device tolerances.
