Overview - Nuvoton NuMicro ISP User Manual

OVERVIEW

®
The NuMicro Family microcontroller (MCU) supports In-System-Programming (ISP) function
allowing the embedded Flash memory to be reprogrammed under software control. ISP is
performed without removing the microcontroller from the system through the firmware and on-chip
connectivity 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 universal
programmer or Nuvoton's NuMicro
configured as Boot from LDROM.
ISP code can be found in the board support package (BSP). Take M480BSP for example, we
supplied ISP_CAN, ISP_HID, ISP_HID_20, ISP_I2C, ISP_RS485, ISP_SPI and ISP_UART
samples as shown in the following link.

The ISPTool repository is available on GitHub, GITEE and GitLab.
