Description
Threshold priority level (a value of 0 to 7, with 0 (default) being the highest priority
level). References with a selection priority value lower than this value are treated as
phase masters (see the Profile Registers (Register 0600 to Register 07FF) section for
the selection priority value).
Description
Controls the phase lock threshold unit scaling.
0 = picoseconds.
1 = nanoseconds.
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.
User-assigned priority level (0 to 7) of the reference associated with Profile 0, which
ranks that reference relative to the others.
