IR
Interrupt request bit
0 : Interrupt not requested
1 : Interrupt requested
(Note 1)
Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns
out to be “0”.
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
interrupt request for that register. For details, see the precautions for interrupts.

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns
out to be “0”.
Note 1: This bit can only be accessed for reset (= 0), but cannot be accessed for set (= 1).
