The LAWBREAKER program is used to test to see if Enforcer properly traps illegal memory accesses. It's and example program and does not test for an MMU. Enforcer does that. But like I said, if the chip says "EC" than it doesn't have a fully functional MMU. It may work most of the time, but there are no promises. Unless you're doing development work, there's little point in having or using an MMU. No user programs use it, and neither does the OS. Er, well, "CPU FASTROM" does, but that's it.
