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 indeterminate.
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 does not generate the
interrupt request for that register. For details, see the precautions for interrupts.
