In normal functional mode, these bits MUST be set to zero.
Lock Interrupt Mask Bit
When this bit is high, it masks the lock status change interrupt.
Reference Change Interrupt Mask Bit
When this bit is high, it masks the reference change interrupt.
Holdover Interrupt Mask Bit
When this bit is high, it masks the holdover entry/exit interrupt.

Lock Change Interrupt Bit
If the device sets this bit to high, the device lock status has changed.
Reference Change Interrupt Bit
If the device sets this bit to high, the selected reference has changed.
Holdover Interrupt Bit
If the device sets this bit to high, the device has entered or recovered from the
holdover/MTIE mode.
