Actually I've already found a workaround.


I planned a hardware IT, whose handler could call a handler of another
hardware IT. I did not know how to disable the second kind of IT while the
first one is served by the same routine. Therefore I wanted to
raise a hard irq from software.
It sounds complicated, doesn't it? :-) Never mind. It works now.
