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.

2 NUVOTON STANDARD ISP CODE
The Nuvoton standard ISP code for NuMicro®MCUs is included in the folder [(2) Nuvoton
Standard ISP Code]. User can program the ISP code into LDROM by using a universal
programmer or Nuvoton’s NuMicro®ICP Programming Tool, and the User Configuration bit ‘CBS’
configured as Boot from LDROM.
The ISPTool samples repository is available on GitHub and GITEE.

3 USING THE ISP PROGRAMMING TOOL IN WINDOWS
The ISP Programming Tool is contained in the folder [(1) Application Program].
3.1 Connecting Interface Selection
User needs to select the ISP connection interface before using the ISP function and makes sure
the IO pins used for communication are connected correctly. For USB interface, an extra entry pin
must be tied to ground pin to enter ISP mode. Please refer to Table 2-1 Pin Definition for all ISP
samples.

3.2 Connecting to the target chip
After clicking the “Connect”button, the ISP tool will keep trying to connect to a target board every
30 ms until the target board is successfully connected or the “Stop”button is clicked. If there is no
response from the target board during connection, please reset the MCU to execute the ISP code.
3.3 Load File
Click the “APROM”or “Data Flash”button to select the image from the pop-up window. Or using
drag & drop function from Windows Explorer to select the image file.

3.4 Setting the User Configuration Bits
After clicking the “Setting”button, a “User Configuration”dialog will open to display all User
Configuration settings. The corresponding “User Configuration”dialog will be displayed
according to the MCU currently connected. Figure 3-6 shows the “User Configuration”setting of
the NUC123AN series MCU.
The ISP tool does not allow user to modify target board boot selection, either. The “Boot Select”
shown in the User Configuration form is for informative purpose only. This setting can be updated
with Nuvoton’s NuMicro®ICP Programming Tool.
