METHOD OF FABRICATING ELECTRONIC DEVICE AND LIMIT VALUE SETTING APPARATUS

摘要

A method of fabricating an electronic device is provided, where the electronic device includes a port, an A/D converter, a memory, and a determination circuit. The determination circuit is configured to determine whether or not there is an abnormality by comparing an A/D converted value as a result of the A/D converter converting a voltage based on a power-supply voltage inputted to the port with a limit value stored in the memory. The method includes a step of inputting a predetermined voltage to the port of the electronic device to be fabricated, and a step of recording an A/D converted value as a result of the A/D converter converting a voltage based on the predetermined voltage inputted to the port as the limit value in the memory.
