10.2.1 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 STM32F446xx datasheets for details on
this parameter.
