3.7 MCUs that are Used in Debugging
3.7.1 Usage in Mass-Production
MCUs that are connected to the E1/E20/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.
Also, as the E1/E20/E2/E2 Lite program is written to the MCU while debugging, do not save the
contents of the MCU flash memory which were used for debugging nor use them as the ROM data for
products.
3.7.2 Standalone Operation
After downloading a load module file to the device to for on-chip debugging, do not check the operation
of this device without E1/E20/E2/E2 Lite.
A device after debugging contains the specific program for on-chip debugging, so it is different from
actual operation.
3.8 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 Renesas Flash Programmer programming software or a flash
programmer, without the emulator connected.
