Bits 5 to 2: Input Clock Status Change (IC[6:3]). Each of these latched status bits is set to 1 when the
corresponding VALSR1 status bit changes state (set or cleared). Each bit is cleared when written with a 1 and not
set again until the VALSR1 bit changes state again. When one of these latched status bits is set, it can cause an
interrupt request on the INTREQ pin if the corresponding interrupt enable bit is set in the IER1 register. See
Section 7.5 for input clock validation/invalidation criteria.

Bit 7: T0 DPLL State Change (STATE). This latched status bit is set to 1 when the operating state of the T0 DPLL
changes. STATE is cleared when written with a 1 and not set again until the operating state changes again. When
STATE is set it can cause an interrupt request on the INTREQ pin if the STATE interrupt enable bit is set in the
IER2 register. The current operating state can be read from the T0STATE field of the OPSTATE register. See
Section 7.7.1.
Bit 6: Selected Reference Failed (SRFAIL). This latched status bit is set to 1 when the selected reference to the
T0 DPLL fails, (i.e., no clock edges in two UI). SRFAIL is cleared when written with a 1. When SRFAIL is set it can
cause an interrupt request on the INTREQ pin if the SRFAIL interrupt enable bit is set in the IER2 register. SRFAIL
is not set in free-run mode or holdover mode. See Section 7.5.3.
Bit 0: Input Clock Status Change (IC9). This latched status bit is set to 1 when the corresponding VALSR status
bit changes state (set or cleared). Each bit is cleared when written with a 1 and not set again until the VALSR2 bit
changes state again. When this latched status bit is set it can cause an interrupt request on the INTREQ pin if the
corresponding interrupt enable bit is set in the IER2 register. See Section 7.5 for input clock validation/invalidation
criteria.
