Required consecutive number of PFD cycles with edges inside lock detect window before the DLD indicates a locked
condition.

If the time difference of the rising edges at the inputs to the PFD is less than the lock detect window time, the digital lock
detect flag is set. The flag remains set until the time difference is greater than the loss-of-lock threshold.
0: high range (default).
1: low range.
Digital lock detect operation.
0: normal lock detect operation (default).
1: disables lock detect.
VCO calibration divider. Divider used to generate the VCO calibration clock from the PLL reference clock.

1
Bit used to initiate the VCO calibration. This bit must be toggled from 0 to 1 in the active registers. To initiate
calibration, use the following three steps: first, ensure that the input reference signal is present; second, set to 0 (if not
zero already), followed by an update bit (Register 0x232, Bit 0); and third, program to 1, followed by another update bit
(Register 0x232, Bit 0).
