Note 1: This bit can only be accessed for reset (= 0), but cannot be accessed for set (= 1).
Note 2: To rewrite the interrupt control register, do so at a point that dose not generate the

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be “0”.
