23.6.1
The above flowchart shows the operation in cable connection. When a USB connection interrupt
occurs, connection can be detected by confirming the status of the USBF_VBUS pin.
Processing by a USB bus connection interrupt is unnecessary for applications in which USB cable
connection is not required to be detected. Prepare processing by a bus reset interrupt.
