LL_EXTI_GenerateSWI_0_31()

__STATIC_INLINE void LL_EXTI_GenerateSWI_0_31

(

uint32_t

ExtiLine

)

Generate a software Interrupt Event for Lines in range 0 to 31.

Note

If the interrupt is enabled on this line in the EXTI_IMR1, writing a 1 to this bit when it is at '0' sets the corresponding pending bit in EXTI_PR1 resulting in an interrupt request generation. This bit is cleared by clearing the corresponding bit in the EXTI_PR1 register (by writing a 1 into the bit) SWIER1 SWIx LL_EXTI_GenerateSWI_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 LL_EXTI_LINE_29 LL_EXTI_LINE_30 LL_EXTI_LINE_31

Please check each device line mapping for EXTI Line availability

LL_EXTI_GenerateSWI_32_63()

__STATIC_INLINE void LL_EXTI_GenerateSWI_32_63

(

uint32_t

ExtiLine

)

Generate a software Interrupt Event for Lines in range 32 to 63.

Note

If the interrupt is enabled on this line inthe EXTI_IMR2, writing a 1 to this bit when it is at '0' sets the corresponding pending bit in EXTI_PR2 resulting in an interrupt request generation. This bit is cleared by clearing the corresponding bit in the EXTI_PR2 register (by writing a 1 into the bit) SWIER2 SWIx LL_EXTI_GenerateSWI_32_63

Parameters

ExtiLine

This parameter can be a combination of the following values: LL_EXTI_LINE_35 LL_EXTI_LINE_36 LL_EXTI_LINE_37 LL_EXTI_LINE_38

Return values

None
