TIM_ExtTRGPolarityThe external Trigger Polarity. This parameter can be one of the following values:
  • TIM_ExtTRGPolarity_Inverted: active low or falling edge active.
  • TIM_ExtTRGPolarity_NonInverted: active high or rising edge active.
ExtTRGFilterExternal Trigger Filter. This parameter must be a value between 0x00 and 0x0F
Return values
None
