In Debug mode, the SWD architecture in the NuMicro? Cortex M0/M4 series needs to keep communicating with the host. Therefore, when debugging, the Cortex? M0/M4 core would disable the Power-down mode.

The VBAT pin primarily supplies power to the RTC module and external low-speed oscillator (LXT), as shown below: If the RTC module is not supplied power by VBAT, its status is uncertain, causing power consumption and affecting the performance of standby power. LXT cannot be used as well because ther...

Yes. If the user needs to read the ADC value of the ACMP pin, the programming flow is not different from the usual ADC setting. The only difference is that the pin function is set to ACMP, instead of ADC.

The GPIO De-bounce function is used to filter noise or interference on the pin. After a voltage signal generates a rising or falling edge, if the time to keep high or low level exceeds the De-bounce time set by the user, a GPIO interrupt occurs. However, there is a limitation related to this functio...

The SWD or ICE interface contains five pins, including VDD, ICE_DAT, ICE_CLK, nReset and VSS. Through the SWD or ICE interface, the user can do MCU programming or debugging with the Nu-Link. Specifically, the nReset pin is used to reset the MCU or initialize SWD and ICE signals. If the Reset pin is ...

Besides the programming and debugging features, the Nu-Link-Me Version 3.0 (or later) supports the Virtual COM Port function. Through the Virtual COM Port, the user can display UART messages on communication software (e.g. HyperTerminal) of a computer. The user needs to switch the SW3 (IDP Switch) o...

Nuvoton provides Nu-Link, Nu-Link-Pro and Nu-Link-Me, through the SWD (Serial Wire Debug) interface, for program debugging and programming in a variety of development environment. Nu-Link: Nu-Link-Pro: Nu-Link-Me: Refer to the following table for differences between functions: Note: The functions ar...

Auto-validation mode: After IN-token is received, data can only be sent when the data payload is equal to the Endpoint Maximum Packet Size (EPMPS). If a user needs to send a short packet of the remaining data in the end of data transmission, the user can set the SHORTTXEN of USBD_EPxRSPCTL[6] to 1. ...

All the Nuvoton NuMicro? Cortex-M4 series BSP (Board Support Packages) include the Cortex?-M4 DSP library and sample code. The files are located at \Library\CMSIS\DSP_Lib\Source, as shown in the figure below. The \Library\CMSIS\DSP_Lib\Examples, DSP sample code provided by ARM? for user reference, i...

When using the PDMA controller of the NuMicro? NUC442/472, the data address that needs to be set is the end address, rather than the starting address set in other series. For example, when the starting address is 0x2000_0000 and the amount of transmission is 0x100, the end address is 0x2000_0100. In...
