5.1
General cautionary notes
5.1.1
Handling of devices which were used for debugging
Do not use devices that were used for debugging in mass-production. This is because writing to the flash
memory of such devices has already proceeded during debugging, so we cannot guarantee the number of
times rewriting of the flash memory can proceed. Debugger errors occur when programming of the flash
memory is no longer possible. Replace the device in such situations.
5.1.2
Quality of flash programming
To improve the quality, follow the guidelines below.
•
Circuits are designed as described in the user's manuals for the MCU and emulator.
•
The MCU, emulator, and software are used as described in respective user's manuals.
•
The supply of power to the user system is stable.
