6
Offset slew limiting
The current closed-loop phase offset is rate limited
5
Frequency lock
The DPLL has achieved frequency lock
4
Phase lock
The DPLL has achieved phase lock
3
Loop switching
The DPLL is in the process of a reference switchover
2
Holdover
The DPLL is in holdover mode
1
Active
The DPLL is active (that is, operating in a closed-loop condition)
0
Freerun
The DPLL is free run (that is, operating in an open-loop condition)

Reserved
Default: 0b
5
Frequency clamped
The upper or lower frequency tuning word clamp is in effect
4
History available
There is sufficient tuning word history available for holdover operation
[3:2]
Active reference priority
Priority value of the currently active reference
00 = highest priority
…
11 = lowest priority
[1:0]
Current active reference
Index of the currently active reference
00 = Reference A
01 = Reference B
10 = Reference C
11 = Reference D

B valid
REFB is valid for use. (It is unfaulted, and its validation timer has expired.)
6
B fault
REFB is not valid for use.
5
B fast
This bit indicates that the frequency of REFB is higher than allowed by its profile settings.
4
B slow
This bit indicates that the frequency of REFB is lower than allowed by its profile settings.
3
A valid
REFA is valid for use. (It is unfaulted, and its validation timer has expired.)
2
A fault
REFA is not valid for use.
1
A fast
This bit indicates that the frequency of REFA is higher than allowed by its profile settings.
0
A slow
This bit indicates that the frequency of REFA is lower than allowed by its profile settings.
0x0D0C
[7:4]
Same as Register 0xDOB[7:4] but for REFD instead of REFB .
[3:0]
Same as Register 0xDOB[3:0] but for REFC instead of REFA.
