MCUs that are Used in Debugging
After debugging with the E2/E2 Lite, if the MCU is disconnected from the emulator and run on its own,
correct operation cannot be guaranteed. To operate the MCU on its own, use the programming software to
re-program the MCU.
MCUs that are connected to the E2/E2 Lite and used in debugging are placed under stress by repeated
programming of flash memory during emulation. Do not use MCUs that were used in debugging in mass-
production for end users.
3.5
Final Evaluation of the User Program
Before entering the mass-production phase, be sure to perform a final evaluation of the program which has
been written to the flash ROM by the programming software, without the E2/E2 Lite connected.
