__HAL_GPIO_EXTI_GET_IT

HAL uses macros for most status gets, IT sets and clears, when it seems missing in context sensitive editor always try __HAL_***_

HAL_EXTI_GetPending() does exactly the same.

I use neither SPL, nor HAL, but it took me only few minutes to find it out. The super "secret magic" formula - looking at register code and thinking!

void EXTI0_IRQHandler(void)

{

 /* EXTI line interrupt detected */

 if(__HAL_GPIO_EXTI_GET_IT(GPIO_PIO_0) != RESET)

 {

  __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIO_0);

 // ... Do processing

 }

}
