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.

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.
