Lock Detector Interval Bits
The binary value of these bits defines the time interval that the output phase detector
must be below the lock detect threshold to declare lock. Unsigned representation of the
LDI bits is defined in 4 ms intervals.
Reserved
In normal functional mode, these bits MUST be set to zero.
Slew Rate Limit Bits
The binary value of these bits defines the maximum rate of DPLL phase change (phase
slope), where the phase represents difference between the input reference and output
feedback clock. Defined in same units as CFN (unsigned).
Reserved
In normal functional mode, these bits MUST be set to zero.
