In the installation folder for the ISP Programming Tool, “config.ini” records PDID (Part Device Identification Number) of all the NuMicro® series. After connection, the ISP Programming Tool will compare the PDID of target chip with the “config.ini”. If the “config.ini” gets lost or the PDID of target chip is not listed in “config.ini”, the "Invalid Chip ID" error message appears on the ISP Programming Tool, or Part No. shows Unknown.

User can download the latest version of NuMicro® ISP Programming Tool from Nuvoton website.
