STM8l定时器在PWM模式下可以进入中断吗

像这样设置可以吗
CLK_PeripheralClockConfig(CLK_Peripheral_TIM2,ENABLE);
  /* TIM2 Channel1 configuration: PB0 */
  GPIO_Init(GPIOB, GPIO_Pin_0, GPIO_Mode_Out_PP_Low_Fast);
  /* Time Base configuration */
  TIM2_DeInit();
  TIM2_TimeBaseInit(TIM2_Prescaler_1, TIM2_CounterMode_Up, TIM2_PERIOD);
  /* Channel 1 configuration in PWM1 mode */
  /* 初始占空比为1%*/
  TIM2_OC1Init(TIM2_OCMode_PWM1, TIM2_OutputState_Enable, 0, TIM2_OCPolarity_High, TIM2_OCIdleState_Reset);
  PWM_TIM2_SetDutyCycle(1);

  TIM2_ITConfig(TIM2_IT_Update , ENABLE);
  TIM2_ARRPreloadConfig(DISABLE);

  /* TIM2 Main Output Enable */
  TIM2_CtrlPWMOutputs(ENABLE);

  /* TIM2 counter enable */
  TIM2_Cmd(ENABLE);

  enableInterrupts();
