22.2.16.2 TIM_ITRxExternalClockConfig
Function Name
void TIM_ITRxExternalClockConfig ( TIM_TypeDef * TIMx,
uint16_t TIM_InputTriggerSource)
Function Description
Configures the TIMx Internal Trigger as External Clock.
Parameters
 TIMx : where x can be 1, 2, 3, 4, 8 or 15 to select the TIM
peripheral.
 TIM_InputTriggerSource : Trigger source. This parameter
can be one of the following values:
 TIM_TS_ITR0 : Internal Trigger 0
 TIM_TS_ITR1 : Internal Trigger 1
 TIM_TS_ITR2 : Internal Trigger 2
 TIM_TS_ITR3 : Internal Trigger 3
Return values
 None.
Notes
 None.

Function Name
void TIM_TIxExternalClockConfig ( TIM_TypeDef * TIMx,
uint16_t TIM_TIxExternalCLKSource, uint16_t TIM_ICPolarity,
uint16_t ICFilter)
Function Description
Configures the TIMx Trigger as External Clock.
Parameters
 TIMx : where x can be 1, 2, 3, 4, 8 or 15 to select the TIM
peripheral.
 TIM_TIxExternalCLKSource : Trigger source. This
parameter can be one of the following values:
 TIM_TIxExternalCLK1Source_TI1ED : TI1 Edge
Detector
 TIM_TIxExternalCLK1Source_TI1 : Filtered Timer
Input 1
 TIM_TIxExternalCLK1Source_TI2 : Filtered Timer
Input 2
