EXTI_ConfigTypeDef structure.
(++) For configurable lines, configure rising and/or falling trigger
"Trigger" member from EXTI_ConfigTypeDef structure.
(++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
member from GPIO_InitTypeDef structure.
(#) Get current Exti configuration of a dedicated line using
HAL_EXTI_GetConfigLine().
