That's the correct number to use.  Have you configured the rest of the
interrupt controller properly?  You need to at least configure SIEXR
for level/edge and SIUMCR to enable the IRQ1 pin.  Of course, this means
you can't enable external snooping due to pin multiplexing, so I hope
that's OK in your system design.
