Nothing is assigned. Write "0" when writing to these bits.
The contents are indeterminate if read.
Note 1: To rewrite the interrupt control register, do so at a point that dose not generate the
interrupt request for that register. For details, see the precautions for interrupts.
Note 2: This bit can only be reset (=0), but cannot be set (=1).
