Functions
Internal routines to manage asynchronous interrupt pin change
This interrupt is connected to a switch and allows to wakeup CPU in low sleep mode. In USB device mode, this wakeup the USB host via a upstream resume. In USB host mode, this wakeup the USB devices connected via a downstream resume.
