FAQ / How to design hardware circuit for USB interface?
https://www.nuvoton.com.cn/support/technical-support/faq/d46fd6c6-04f1-11ea-b113-05daf7eedf03/
How to design hardware circuit for USB interface? 1423411200000 The NuMicro™ Cortex-M0 family supports powerful full-speed USB devices embedded 1.5kΩ pull-up resistor and LDO 3.3V output. Please refer to the picture below and note that the impedance of D- and D+ traces should match 45Ω. Also, 1.5kΩ pull-up resistor and LDO 3.3V output can be controlled by DPPU bit and PWRDN bit of USB_ATTR respectively. Note: VDD33 is only used by the internal circuit of NuMicro™ Cortex-M0 Series and must be connected with 1uF capacitance for voltage stability.

FAQ / Can the VBAT pin be floating if the RTC function is not required?
https://www.nuvoton.com.cn/support/technical-support/faq/d6647aea-04f1-11ea-b113-05daf7eedf03/
VBAT Can the VBAT pin be floating if the RTC function is not required? 1467020552555 No. The VBAT pin is used to supply power to a RTC module, as shown below. When the VBAT pin is floating, the RTC module condition is unknown and will generate power to affect the standby power performance. In this case, it is recommended to connect the VBAT withVDD to prevent the power consumption of the RTC module from being increased.
