I'm working on a boot loader for the 'm128 and got curious about illegal op-codes. Does anybody know what the real hardware does when it executes an unimplemented code? Studio sim seems to treat the all ones (0xffff) case as a no-op but I don't have the real hardware handy at the moment to see what it does. Thanks in advance for any insights. Bruce
