Mass Storage ISP is one In-System Programming methodology to support download firmware to APROM of NuMicro® Family through mass-storage interface. By using mass-storage interface, we don’t need to provide any tool or driver for PC to support firmware download.

For a device which supports Mass Storage ISP, user just needs to plug-in the device by USB cable. Then PC will recognize it as a mass-storage disk and user just need to “COPY” a
binary firmware image to the mass-storage disk to do “firmware download”.
