LOS
SYNC
SYNC Indicates synchronization has been achieved
0 = Not synchronized
1 = Synchronized
LOS
Loss of signal of the selected reference
0 = No Loss
1 = Loss (Indicate loss of signal, freerun, pseudo holdover and holdover)
LOL
Loss of lock (Failure to achieve or maintain lock)
0 = No loss of lock
1 = Loss of lock (Indicate loss of lock, freerun, pseudo holdover and holdover)
OOP
Out of pull-in range. Indicate the frequency offset of the selected reference input is out of pull-in range.
1 = Out of pull-in range
0 = In range
SAP
Indicates the output clocks have stopped following the selected reference, caused by out of pull-in
range
1 = Stop following at pull-in range boundary
0 = Following
FEE
Frame edge error. Indicates whether an error occurs in the frame edge selection process in slave
mode or master phase align mode. For timing generator T0 only.
1 = Frame edge error occurs
0 = No frame edge error occurs
DHT
Device Holdover History tracking
1 = Device holdover history is being tracked.
0 = Device holdover history is based on the last available history.
HHA Holdover History Availability. Config Control_Mode register to select which of holdover history is used.
Device Holdover History or User Specified History.
1 = Available
0 = Not available
