APPENDIX B User System Specifications
I Design Precautions
To operate the evaluation MCU on the user system without connecting the emulator, you must
adequately terminate the input terminals of the evaluation MCU that are connected to the
emulator interface on the user system.
A switching circuit may therefore be necessary on the user system. Be careful on this point
during the design process.
Table B-2 "Emulator Interface Terminal Termination (DSU-3)" and Table B-3 "Emulator Interface
Terminal Termination (DSU-4)" summarize the termination of emulator interface terminals.

Because incorrectly connected probes may cause a short-circuit or
reverse connection between power supply and GND in operation, to
ensure safety, insert a protective circuit such as a fuse into power
supply pattern. Doing so may result in device problems or fire.
