Nuvoton Nu-Link Debug Adapter User Manual
Oct 24, 2019 - 16 - Revision V1.01
3.3 Wide Voltage Programming
The Nu-Link-Pro supports the wide voltage programming function, by which the development software
tool can adjust the SWD port voltage as 1.8V, 2.5V, 3.3V, or 5.0V. As shown in Figure 4-2, the pins
that can be controlled include VCC, ICE_DAT, ICE_CLK, and /RESET.
Also, as shown in Figure 2-1, the Nu-Link-Pro provides a set of SWD I/O Voltage LEDs and SWD
Power Output LEDs for checking the SWD port voltage. Refer to Table 2-3 for more details about the
LED status,
The Nu-Link-Me supports the wide voltage programming function, by which the resistor JPR1 can
adjust the SWD port voltage as 3.3V or 5.0V. As shown in Figure 4-2, the pins that can be controlled
include VCC, ICE_DAT, ICE_CLK, /RESET, ICE_RX and ICE_TX.
The Nu-Link2-Me supports the wide voltage programming function, by which the resistor ICEJPR1 can
adjust the SWD port voltage as 1.8V, 3.3V or 5.0V. As shown in Figure 4-2, the pins that can be
controlled include VCC, ICE_DAT, ICE_CLK, /RESET, ICE_RX/PASS, ICE_TX/Fail, BUSY and
START.
3.4 Installing the Nu-Link Adapter Driver
The Nu-Link Adapter supports a variety of functions and third-party software tools (e.g. Keil MDK and
IAR EWARM). After the software programs are installed, the drivers are also required. You can use
the following links: Nu-Link Adapter Driver for Keil MDK and Nu-Link Adapter Driver for IAR EWARM
to install the latest version. For details about software setup, please refer to section 4.2.
