DMM (Dynamic Memory Modification): Function that rewrites the contents of the RAM during program
execution
4. The latest 8 trace conditions are traced.
The trace conditions (branch source, branch destination, write access) can be set.
5. The trace function of the Nx85ET core is realized by using the trace interface. This emulator does not
feature a trace interface, so the trace function cannot be used.
