What the "Exception Address" mean?

In SOPC Builder, at the "More CPU settings" menu, there has a table which contains a selection "Exception Address".

I don't know its mean and what function it does. Anyone who knows can tell me.

Thanks.

    If an ecternal interrupt or a trap occurs, the program counter jumps to this address. So you can do the interrupt handling over there.

    See documentation included...

    p 2-4 and 3-13 in the Nios II processor reference handbook - if the pages have changed for the new version, please just do a search in the doc for exception address.

    ans p 4-31 in the Nios II software developers handbook. again, search if the pages have changed.
