LL_LPTIM_ConfigTrigger() - syntax, references, description

Configure the external trigger used as a trigger event for the LPTIM.

Syntax

__STATIC_INLINE void LL_LPTIM_ConfigTrigger(LPTIM_TypeDef *LPTIMx, uint32_t Source, uint32_t Filter, uint32_t Polarity);

Arguments

LPTIMx

Low-Power Timer instance

Source

This parameter can be one of the following values: @arg LL_LPTIM_TRIG_SOURCE_GPIO @arg LL_LPTIM_TRIG_SOURCE_RTCALARMA @arg LL_LPTIM_TRIG_SOURCE_RTCALARMB @arg LL_LPTIM_TRIG_SOURCE_RTCTAMP1 @arg LL_LPTIM_TRIG_SOURCE_TIM1_TRGO @arg LL_LPTIM_TRIG_SOURCE_TIM5_TRGO

Filter

This parameter can be one of the following values: @arg LL_LPTIM_TRIG_FILTER_NONE @arg LL_LPTIM_TRIG_FILTER_2 @arg LL_LPTIM_TRIG_FILTER_4 @arg LL_LPTIM_TRIG_FILTER_8

Polarity

This parameter can be one of the following values: @arg LL_LPTIM_TRIG_POLARITY_RISING @arg LL_LPTIM_TRIG_POLARITY_FALLING @arg LL_LPTIM_TRIG_POLARITY_RISING_FALLING

Return value

Notes

This function must be called when the LPTIM instance is disabled. An internal clock source must be present when a digital filter is required for the trigger. CFGR TRGFLT LL_LPTIM_ConfigTrigger\n CFGR TRIGEN LL_LPTIM_ConfigTrigger
