Parameters:

hexti	Exti handle.
Edge	Specify which pending edge as to be clear. This parameter can be one of the following values: EXTI_TRIGGER_RISING_FALLING This parameter is kept for compatibility with other series.

Return values:

None.

uint32_t HAL_EXTI_GetPending	(	EXTI_HandleTypeDef *	hexti,
		uint32_t	Edge
	)

Get interrupt pending bit of a dedicated line.

Parameters:
