LL_EXTI_ClearFlag_0_31()

__STATIC_INLINE void LL_EXTI_ClearFlag_0_31

(

uint32_t

ExtiLine

)

Clear ExtLine Flags for Lines in range 0 to 31.

Note

This bit is set when the selected edge event arrives on the interrupt line. This bit is cleared by writing a 1 to the bit. @rmtoll PR PIFx LL_EXTI_ClearFlag_0_31

Parameters

ExtiLine

This parameter can be a combination of the following values: LL_EXTI_LINE_0 LL_EXTI_LINE_1 LL_EXTI_LINE_2 LL_EXTI_LINE_3 LL_EXTI_LINE_4 LL_EXTI_LINE_5 LL_EXTI_LINE_6 LL_EXTI_LINE_7 LL_EXTI_LINE_8 LL_EXTI_LINE_9 LL_EXTI_LINE_10 LL_EXTI_LINE_11 LL_EXTI_LINE_12 LL_EXTI_LINE_13 LL_EXTI_LINE_14 LL_EXTI_LINE_15 LL_EXTI_LINE_16 LL_EXTI_LINE_18 LL_EXTI_LINE_19(*) LL_EXTI_LINE_20(*) LL_EXTI_LINE_21 LL_EXTI_LINE_22
