WDT Reset, POR, LVR, Reset What should user do if the WDT (Watchdog Timer) Reset of the NUC505 does not work properly? 1543385234724 When the WDT Reset occurs in the NUC505, the hardware mechanism of the WDT will pull the voltage of reset pin low to trigger reset; if the voltage of the Reset pin cannot be pulled low, the reset will not be triggered normally, and a hardfault may occur. Therefore, it is necessary to modify the circuit design. Refer to the design of the NUC505 development board for the circuit of the reset pin using the pull-up resistance value of 1kΩ, as shown in the following circuit diagram.

USB, Full Speed device, High Speed device How to set a USB device as full speed device or a high speed device? 1516004037099 Among the NuMicro® Cortex®-M4 microcontrollers (MCUs), the NUC505, NUC400, and M480 series USB devices support full speed and high speed devices. Users can select full speed or high speed devices by setting registers. In the NUC505 and NUC400 series, the register is CURSPD (USBD_OPER [2]), as shown in Figure 1. In the M480 series, the register is CURSPD (HSUSBD_OPER [2]), as shown in Figure 2.

Häufig gestellte Fragen / Why can’t some BSP samples be executed in Free run mode (boot from SPI) in the IAR environment?
https://www.nuvoton.com.cn/support/technical-support/faq/d92a9f2f-04f1-11ea-b113-05daf7eedf03/
NUC505, IAR Why can’t some BSP samples be executed in Free run mode (boot from SPI) in the IAR environment? 1543307177397 Since the NUC505 is internally SPI Flash, the execution speed is slow. To increase the execution speed in the Debug mode, use the sram.icf file in the Linker to set the RAM at 0x10000-0x1FFFF, and put the code into the SRAM as shown in Figure 1. However, this setting can only be executed in Debug mode. When switching to Free run mode (boot from SPI), user must modify the icf file in Linker and place the RAM at the correct address. Users can set RAM address by directly using the spirom.icf in the BSP, as shown in Figure 2. The path is NUC505BSPV3.02.000\SampleCode\BootTemplate\CriticalOnSRAM\IAR.
