To enable the MMU

1 Make sure that the tranlation tables are valid. These translation tables must be
set up by your target system software.
2 Enable the MMU in the emulator by answering the "Enable the MMU?"
question in the emulator configuration or by loading the translation control
register.
When you enable the MMU, the debugger status line will change from
"68EC030" to "68030."
3 Load the translation tables into the deMMUer by entering the following
command on the debugger's command line:
Trace deMMUer Load Verbose
4 Enable the deMMUer by entering the following command on the debugger's
command line:
Trace deMMUer Enable
After the deMMUer is loaded, any change to the MMU will make the
deMMUer out of date. If you change the MMU, remember to re-load the
deMMUer.
The target program will be interrupted while the deMMUer is being loaded.
The analyzer will produce strange results if it is making a trace while the
deMMUer is being loaded.
