Bit Name
Description
0x0600 [7] Phase lock scale Controls the phase lock threshold unit scaling.
0 = picoseconds.
1 = nanoseconds.

Promoted priority
User assigned priority level (0 to 7) of the reference associated with Profile 0 while that
reference is the active reference. The numeric value of the promoted priority must be less
than or equal to the numeric value of the selection priority.
[2:0]
Selection priority
User assigned priority level (0 to 7) of the reference associated with Profile 0, which ranks
that reference relative to the others.
