Debugging Memory Map
The DMM GUI
717 Microcontrollers Debugger Manual
Pressing the Revert to Default button removes (after a warning dialog) the current setup
(usually saved in the current project) and retrieves the default (factory) setup from an
internal database.

Figure 33.2 shows the DMM Memory map dialog box.
Figure 33.2 DMM Memory Address Range Edition Dialog box
The Enable memory module option checkbox maps the module/memory range in the
debugger. Unchecking this option makes the module completely transparent for the DMM
and the debugger.
The Start edit box contains the first address of a memory range and the End edit box
contains the last address of a memory range.
Range boundaries are always limited to an overlapped range with a bigger priority.
For example, if 2 bytes are defined in a range which overlaps another range, accessing
these 2 bytes is performed using the type and rules of this 2-byte range. The memory on
both sides of these 2 bytes is accessed using the type and rules of the overlapped range.
NOTE The Start–End range is a range address for a Type and for a Priority .
Internally, ranges can overlap only if they are of the same type and of the same
priority. The debugger always reads with rules of the range with the highest
priority.
