  • TIM_ExtTRGPolarity_Inverted: active low or falling edge active.
  • TIM_ExtTRGPolarity_NonInverted: active high or rising edge active.
ExtTRGFilter,:External Trigger Filter. This parameter must be a value between 0x00 and 0x0F
Return values:
None

Parameters:
TIMx,:where x can be 1, 2, 3, 4, 5, 6, 7 or 8 to select the TIM peripheral.
TIM_TRGOSource,:specifies the Trigger Output source. This parameter can be one of the following values:
  • For all TIMx
    • TIM_TRGOSource_Reset: The UG bit in the TIM_EGR register is used as the trigger output(TRGO)
    • TIM_TRGOSource_Enable: The Counter Enable CEN is used as the trigger output(TRGO)
    • TIM_TRGOSource_Update: The update event is selected as the trigger output(TRGO)
  • For all TIMx except TIM6 and TIM7
    • TIM_TRGOSource_OC1: The trigger output sends a positive pulse when the CC1IF flag is to be set, as soon as a capture or compare match occurs(TRGO)
