+ * + Initialization and de-initialization functions
+ * + IO operation functions
+ *
+ @verbatim
+ ==============================================================================
+ ##### EXTI Peripheral features #####
+ ==============================================================================
+ [..]
+ (+) Each Exti line can be configured within this driver.
+
+ (+) Exti line can be configured in 3 different modes
+ (++) Interrupt
+ (++) Event
+ (++) Both of them
+
+ (+) Configurable Exti lines can be configured with 3 different triggers
+ (++) Rising
+ (++) Falling
+ (++) Both of them
+
+ (+) When set in interrupt mode, configurable Exti lines have two different
+ interrupts pending registers which allow to distinguish which transition
+ occurs:
+ (++) Rising edge pending interrupt
+ (++) Falling
+
+ (+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
+ be selected through multiplexer.
+
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+
+ (#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
+ (++) Choose the interrupt line number by setting "Line" member from
+ EXTI_ConfigTypeDef structure.
+ (++) Configure the interrupt and/or event mode using "Mode" member from
+ 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().
+ (++) Provide exiting handle as parameter.
+ (++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
+
+ (#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
+ (++) Provide exiting handle as parameter.
+
+ (#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
+ (++) Provide exiting handle as first parameter.
+ (++) Provide which callback will be registered using one value from
+ EXTI_CallbackIDTypeDef.
+ (++) Provide callback function pointer.
+
+ (#) Get interrupt pending bit using HAL_EXTI_GetPending().
+
+ (#) Clear interrupt pending bit using HAL_EXTI_GetPending().
+
+ (#) Generate software interrupt using HAL_EXTI_GenerateSWI().
