void TIM_SelectOutputTrigger_mort ( TIM_TypeDef_mort *  TIMx,
uint16_t  TIM_TRGOSource 
)

Selects the TIMx Trigger Output Mode.

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_MORT: The UG bit in the TIM_EGR register is used as the trigger output(TRGO)
    • TIM_TRGOSource_Enable_MORT: The Counter Enable CEN is used as the trigger output(TRGO)
    • TIM_TRGOSource_Update_MORT: The update event is selected as the trigger output(TRGO)
  • For all TIMx except TIM6_MORT and TIM7_MORT
    • TIM_TRGOSource_OC1_MORT: 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)
    • TIM_TRGOSource_OC1Ref_MORT: OC1REF signal is used as the trigger output(TRGO)
    • TIM_TRGOSource_OC2Ref_MORT: OC2REF signal is used as the trigger output(TRGO)
    • TIM_TRGOSource_OC3Ref_MORT: OC3REF signal is used as the trigger output(TRGO)
    • TIM_TRGOSource_OC4Ref_MORT: OC4REF signal is used as the trigger output(TRGO)
    Return values:
    None

void TIM_SelectSlaveMode_mort ( TIM_TypeDef_mort *  TIMx,
uint16_t  TIM_SlaveMode 
)

Selects the TIMx Slave Mode.

Parameters:
TIMx,:where x can be 1, 2, 3, 4, 5, 8, 9 or 12 to select the TIM peripheral.
TIM_SlaveMode,:specifies the Timer Slave Mode. This parameter can be one of the following values:

  • TIM_SlaveMode_Reset_MORT: Rising edge of the selected trigger signal(TRGI) reinitialize the counter and triggers an update of the registers
  • TIM_SlaveMode_Gated_MORT: The counter clock is enabled when the trigger signal (TRGI) is high
  • TIM_SlaveMode_Trigger_MORT: The counter starts at a rising edge of the trigger TRGI
  • TIM_SlaveMode_External1_MORT: Rising edges of the selected trigger (TRGI) clock the counter
Return values:
None
