Ok, another question: the stacked PC. How does the 68040 behave, if I modify
the stacked PC inside the bus error handler to some other (e.g. further)
address and resume? I'd suppose that the CPU would first restart the
instruction that caused the fault, and then execute the instruction pointed
to by the PC. Is this so? Would this fire up the trace-on-change-of-flow
exception, in case such tracing is enabled?
