Wire Debug) signal interface and can be applied to the development of Nuvoton NuMicro™ Family chips. As shown in Table 2-1, there are three types of the Nu-Link Debug Adapter in accordance with different specifications, including Nu-Link-Pro, Nu-Link, and Nu-Link-Me. The three types are called “Nu-Link Adapter”... -
Page 4: Hardware Specifications
The Nu-Link Adapter provides an USB connector and a SWD signal interface for connecting to the target chip. The user can connect the Nu-Link Adapter to an USB port of a PC to debug and program target chips through the development software tools. As shown in Table 2-1, there are three specifications for the Nu-Link Adapter, in which debugging, Online/Offline Programming, and SWD I/O voltage settings may be supported depending on the specifications (refer to the +Appendix for details). -
Page 5: Nu-Link
The Nu-Link is a basic debugger and programmer with debugging and online/offline programming functions. As shown in Figure 2-2, the Nu-Link includes an USB port that can be connected to a computer host, a set of Status LEDs, an offline programming button, and a SWD port that can be connected to a target chip for debugging and programming (the default voltage of the SWD port as 5.0V). -

Nuvoton Nu-Link Debug Adapter User Manual Main Functions The Nu-Link Adapter provides complete debugging and programming functions for NuMicro™ Family and supports a number of third-party development tools. The detailed function support is listed in Table 3-1. Table 3-1Nu-Link Adapter Functions... -
Page 9: Debugging
In Debug mode, the user can add breakpoints in the code for debugging. During the real-time simulation of the Nu-Link Adapter, the chip simulation will be stopped at a specific breakpoint. Figure 3-1 shows the breakpoint settings in Keil RVMDK Debug mode. The red labels on lines 052 and 059 indicate the breakpoints inserted;... - Page 10 Double-clicking a “register value” will open the register control details, as shown in the right part of Figure 3-3. The “register value” or “control value” can be modified directly. The Nu-Link Adapter will then modify the content of the target chip.

Page 11: Semihost
When using the Semihost function, the message of the NuMicro™ Family microcontroller can be output through UART to the debug window by the Nu-Link Adapter. That is, the message is output without the GPIO. Figure 3-4 shows the debug messages in the “UART #1” form, which are the messages output by the Nu-Link Adapter. -

Page 15: Installation And Setup
Connecting to the Nu-Link Adapter As shown in Figure 4-1, the Nu-Link Adapter is a bridge between an USB and the SWD interface, by which software tools can debug and program the target chip through an USB. The user can plug the Nu-Link Adapter into an USB port of a PC directly or connect using the USB connector. -
