If the USB cable enters the disconnection state from the connection state in an application (self
powered) where USB module stop or power-down mode is not used, perform the operation as
shown in figure 14.5. In bus-powered mode, the power is automatically turned off when the
USB cable is disconnected and the following processing is not required.
Note:
Disconnect the USB cable
VBUS interrupt occurs

Reset the UDC core
VBUS interrupts in the USB module cannot be detected in power-down mode
or in the USB module stop state.
