User memories
You can map external memories segments in two different ways:
•
•
In both cases all emulation features (such as breakpoints, trace, memory window,
memory access control) are available.
Some differences in behavior must however be considered.
When mapping external segments as system memories, the following points must
be taken into account:
•
•
In order to avoid problems of external memory interface configuration, we advise
you to debug your application program in two steps:
1

either you can use the on-emulator memories to emulate those segments. In
this case, you define them as system memories,
or you can use the memories located on your application board. In this case,
you define them as user memories.
When external memory is accessed through port 0 or port 1, the emulator will
not detect if the ports are incorrectly configured as alternate functions to
access external memories. If this configuration has not been handled correctly,
your application program may run correctly with system memories, but it will
not run with user memories or with the chip itself.
The emulator will function at its maximum operation speed without need of wait
states for the system memories access whereas the wait states could be
needed for the chip to access your application memories.
The first step is to debug your program using the emulation memories.
The second step is to debug your program with the application memories to
ensure that ports and access configurations are correct.
