8.2 External interrupt/event controller (EXTI)
The external interrupt/event controller consists of up to 23 edge detectors for generating
event/interrupt requests. Each input line can be independently configured to select the type
(interrupt or event) 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
8.2.1 EXTI main features
The main features of the EXTI controller are the following:
• independent trigger and mask on each interrupt/event line
• dedicated status bit for each interrupt line
• generation of up to 23 software event/interrupt requests
• detection of external signals with a pulse width lower than the APB2 clock period. Refer
to the electrical characteristics section of the STM32F20x and STM32F21x datasheets
for details on this parameter.
