IR Interrupt request bit
Nothing is assigned.
These bits can neither be set nor reset. When read, their contents are
indeterminate.
Note 1:
This bit can only be reset (= 0), but cannot be set ( = 1).
Note 2:
When rewriting the interrupt control register, do so at a point that does not
generate an interrupt requst for that register. For details, see the interrupt
precaution section.
