Enables dc offset in single-ended CMOS input mode to prevent chattering when ac-coupled and input is lost.
[7] = 0; disable dc offset (default).
[7] = 1; enable dc offset.
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 are 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.
[4] = 0; high range (default).
[4] = 1; low range.
Digital lock detect operation.
[3] = 0; normal lock detect operation (default).
[3] = 1; disable lock detect.
