VCO Calibration Override/Done.
When vcocalov = 0 the internal VCO calibration results may be viewed by
reading the vcocal register. When vcocalov = 1 the VCO results may be
overridden externally through the SPI by writing to the vcocal register. Reading
this bit gives 1 if the calibration process has been finished.
