B counter is divided by 1. This allows the prescaler setting to determine the divide for the
N divider.

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.
0 = Normal Lock Detect Operation (Default).
1 = Disable Lock Detect.
