The above flowchart shows the operation in the case of in section 20.7, Example of External
Circuitry for USB Function Controller.
In applications that do not require USB cable connection to be detected, processing by the USB
bus connection interrupt is not necessary. Preparations should be made with the bus reset interrupt.
For details, see section 20.7, Example of External Circuitry for USB Function Controller.
