Detailed Description

Function Documentation

LL_EXTI_DisableFallingTrig_0_31()

__STATIC_INLINE void LL_EXTI_DisableFallingTrig_0_31

(

uint32_t

ExtiLine

)

Disable ExtiLine Falling Edge Trigger for Lines in range 0 to 31.

Note

The configurable wakeup lines are edge-triggered. No glitch must be generated on these lines. If a Falling edge on a configurable interrupt line occurs during a write operation in the EXTI_FTSR register, the pending bit is not set. Rising and falling edge triggers can be set for the same interrupt line. In this case, both generate a trigger condition. FTSR1 FTx LL_EXTI_DisableFallingTrig_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
