Reserved. 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.
Slew Rate Limiter Interrupt Mask Bit: When this bit is high, it masks the slew rate
interrupt.

Reserved. In normal functional mode, these bits MUST be set to zero.
Interrupt Clear Bits: Writing a “1” to any bit in this register will clear the
corresponding bit in the Interrupt Register (IR). The Interrupt Clear Register is
self-clearing, i.e., once it has completed its action, the ICR register bit returns to 0.
