LL_TIM_SetClockSource
Function name
__STATIC_INLINE void LL_TIM_SetClockSource
(TIM_TypeDef * TIMx, uint32_t ClockSource)
Function description
Set the clock source of the counter clock.
Parameters
TIMx: Timer instance
ClockSource: This parameter can be one of the following
values:
LL_TIM_CLOCKSOURCE_INTERNAL
LL_TIM_CLOCKSOURCE_EXT_MODE1
LL_TIM_CLOCKSOURCE_EXT_MODE2
Return values
None:
Notes
when selected clock source is external clock mode 1, the
timer input the external clock is applied is selected by calling
the LL_TIM_SetTriggerInput() function. This timer input must
be configured by calling the LL_TIM_IC_Config() function.
