Frequency synthesizer calibration result register. Capacitor
array setting for VCO coarse tuning.
Fast frequency hopping without calibration for each hop can
be done by calibrating upfront for each frequency and saving
the resulting FSCAL3, FSCAL2and FSCAL1register values.
Between each frequency hop, calibration can be replaced by
writing the FSCAL3, FSCAL2and FSCAL1register values
corresponding to the next RF frequency.
Note: This register will be in its reset state when returning to active mode from PM2 and PM3.
