ISP Programming ToolOct. 15, 2019 Page 3 of 9 Rev 3.05ISP PROGRAMMING TOOL USER MANUAL1 OVERVIEWThe NuMicro® Family microcontroller (MCU) supports In-System-Programming (ISP) functionallowing the embedded Flash memory to be reprogrammed under software control. ISP isperformed without removing the microcontroller from the system through the firmware and on-chipconnectivity interface, such as UART, USB, I²C, SPI, and CAN.Before using the ISPTool, user needs to program the ISP code into LDROM by using a universalprogrammer or Nuvoton’s NuMicro® ICP Programming Tool, and the User Configuration bit ‘CBS’configured as Boot from LDROM.ISP code can be found in the board support package (BSP). Take M480BSP for example, wesupplied ISP_CAN, ISP_HID, ISP_HID_20, ISP_I2C, ISP_RS485, ISP_SPI and ISP_UARTsamples as shown in the following link.https://github.com/OpenNuvoton/M480BSP/tree/master/SampleCode/ISPThe ISPTool repository is available on GitHub, GITEE and GitLab.Please check the following link to get the latest update.https://github.com/OpenNuvoton/ISPToolhttps://gitee.com/OpenNuvoton/ISPToolhttps://gitlab.com/OpenNuvoton/nuvoton-tools/ISPTool
