--- Comment #6 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
all good, unit test created and passes

-        # trap address
+        # trap address, including KAIVB override
         comb += nia_o.data.eq(trap_addr)
+        comb += nia_o.data[13:].eq(self.kaivb[13:])

sc *also* is redirected as well because it uses the exact same TRAP
system

            #################
            # SC.  v3.0B p952

            with m.Case(MicrOp.OP_SC):
                # jump to the trap address, return at cia+4
                self.trap(m, 0xc00, cia_i+4)
                self.msr_exception(m, 0xc00)
