Reverse translations are made in real time

The deMMUer performs its reverse translations without slowing down the
measurement. For this reason, the analyzer that obtains its information from the
deMMUer is able to provide its full feature set.

Settings→DeMMUer→Enable or set demmuer off. Your analyzer receives
physical addresses if the MMU is enabled. The analyzer can only show
hexadecimal values for those physical addresses. They may not correspond to
the logical addresses of your program code. Note that until the MMU is
enabled in hardware and software, addresses will be logical. Only after the
MMU is enabled is there a distinction between physical and logical.
Settings→DeMMUer→Enable or set demmuer on. Your analyzer receives
logical addresses translated by the deMMUer according to the tables in place
when you last loaded the deMMUer. The DeMMUer must be loaded with data
to reverse translations before it can be enabled.
Settings→DeMMUer→Load from Memory or load demmuer. The
emulator reads the MMU registers and interprets the translation tables to load
the deMMUer. The deMMUer is also enabled after it is loaded.
Settings→DeMMUer→Load from Memory... This opens a dialog box in
which you can specify values to override the present values in MMU registers
when loading the DeMMUer.
