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.
Reserved
In normal functional mode, this bit MUST be set to one.
