ISP PROGRAMMING TOOL USER MANUAL
1 OVERVIEW
The “ISP” (In-System Programming) tool allows the embedded Flash memory to be
reprogrammed under software control through the firmware using on-chip connectivity interface,
such as UART and USB, without removing any microcontroller from the system.
For NuMicro®Family microcontroller (MCU) products, the on-chip Flash memory is partitioned into
three blocks: APROM, Data Flash and LDROM. The APROM saves the user application program
developed for a specific application; the Data Flash provides storage for nonvolatile application
data; and the LDROM saves the ISP code for MCU to update its APROM/Data Flash/CONFIG.
User can update the MCU’s APROM, Data Flash, and User Configuration bits with Nuvoton
standard ISP code programmed in LDROM easily by using the ISP function.
