Figure 79. USB Interrupt System
The macro distinguishes between USB General events in opposition with USB Endpoints events
that are relevant with data transfers relatives to each endpoint.
Figure 80. USB General interrupt vector sources
Each of these interupts are time-relative events that will be detected only if the USB clock is
enabled (FRZCLK bit set), except for the WAKEUP interrupt that will trigger each time a state
change is detected on the data lines.
This asynchronous interrupt WAKEUP allows to wake-up a device that is in power-down mode,
generally after that the USB has entered the Suspend state.
