14.8.13 USB External Circuit Example
The USB external circuit examples are used for reference only. In actual board design, carefully
check the system operation.
In addition, the USB external circuit examples cannot guarantee the correct system operation. The
user must individually take measures against external surges or ESD noise by incorporating
protective diodes or other components if necessary.
