I had a sharp look at it... ;)
Actually, I looked through the datasheet three times, and did not find
anything. Then I looked at the IRQ routing picture until I had an idea
of how it is supposed to work and the solution was becoming clear. The
register descriptions made me believe it could work, and testing
confirmed this.
