4
Force release of distribution sync
when PLL2 is unlocked
0 (default): distribution is held in sync (static) until the output PLL locks. Then it is
automatically released from sync with all dividers synchronized.
1: overrides the PLL2 lock detector state; forces release of the distribution from
sync.
3
Reserved
0 (default): value must remain 0.
2
Force VCO to midpoint frequency
Selects VCO control voltage functionality.
0 (default): normal VCO operation.
1: forces VCO control voltage to midscale.
1
Calibrate VCO (not autoclearing)
1: initiates VCO calibration (this is not an autoclearing bit).
0: resets the VCO calibration.
