Bit 7: Frame-Sync Input Monitor Alarm (FSMON). This real-time status bit indicates the current status of the
frame-sync input monitor. See Section 7.9.6.
0 = No alarm
1 = Alarm
Bit 6: T4 DPLL Lock Status (T4LOCK). This real-time status bit indicates the current phase-lock status of the T4
DPLL. See Sections 7.5.3 and 7.7.6.
0 = Not locked to selected reference
1 = Locked to selected reference
Bit 5: T0 DPLL Frequency Soft Alarm (T0SOFT). This real-time status bit indicates whether the T0 DPLL is
tracking its reference within the soft alarm limits specified in the SOFT[6:0] field of the DLIMIT3 register. See
Section 7.7.6.
0 = No alarm; frequency is within the soft alarm limits
1 = Soft alarm; frequency is outside the soft alarm limits
Bit 4: T4 DPLL Frequency Soft Alarm (T4SOFT). This real-time status bit indicates whether the T4 DPLL is
tracking its reference within the soft alarm limits specified in the SOFT[6:0] field of the DLIMIT3 register. See
Section 7.7.6.
0 = No alarm; frequency is within the soft alarm limits
1 = Soft alarm; frequency is outside the soft alarm limits
Bits 2 to 0: T0 DPLL Operating State (T0STATE[2:0]). This real-time status field indicates the current state of the
T0 DPLL state machine. Values not listed below correspond to invalid (unused) states. See Section 7.7.1.
001 = Free-run
010 = Holdover
100 = Locked
101 = Prelocked 2
110 = Prelocked
111 = Loss-of-lock
