External interrupt/event controller (EXTI)

The external interrupt/event controller consists of up to 20 edge detectors in connectivity
line devices, or 19 edge detectors in other devices for generating event/interrupt requests.
Each input line can be independently configured to select the type (event or interrupt) and
the corresponding trigger event (rising or falling or both). Each line can also masked
independently. A pending register maintains the status line of the interrupt requests
