Description
The current closed-loop phase offset is rate limited.
A phase build-out transition was made to the currently active reference.
The DPLL has achieved frequency lock.
The DPLL has achieved phase lock.
The DPLL is in the process of a reference switchover.
The DPLL is in holdover mode.
The DPLL is active (that is, operating in a closed-loop condition)
The DPLL is free running (that is, operating in an open-loop condition)
The upper or lower frequency tuning word clamp is in effect.
There is sufficient tuning word history available for holdover operation.
Priority value of the currently active reference.
000 = highest priority.
111 = lowest priority.
Index of the currently active reference.
000 = Reference A.
001 = Reference AA.
010 = Reference B.
011 = Reference BB.
100 = Reference C.
101 = Reference CC.
110 = Reference D.
111 = Reference DD.
