Ooops yes you are correct, I didn't see that part of his post.

What happens if you do this instead? IOWR(FIR_INTERRUPT_0_BASE, 0x7C, 0x3)

Also which tool are you using? SOPC Builder or Qsys? The behavior accessing native slaves is slightly different between the two tools depending on the data width of the master and slave.
