interrupt status register

[Guillaume]

I need to implement the SCU interrupt status register, but the this register is under documented. I know that you can't write to it (according to the SCU final specifications), but I don't know what it should return when it is read.

If I understand the SCU manual, it should tell if an interrupt occurs, but what happen if the interrupt is masked and when did the value is reset?

To me the bit of the currently executed interrupt is raised here, so it won't be set if the interrupt is masked ...

... the currently executed interrupt ...

Does the value of the register is cleared after the interrupt execution?

Yes, otherwise it'll fastly become messy
