关于STM32F407的TIM9~TIM14定时器

在写stm32f407定时器中断时，用到tim10定时器，在stm32f4xx.h文件中发现了TIM9~TIM14定时器中断名字如下：
TIM1_BRK_TIM9_IRQn       = 24,    /*!< TIM1 Break interrupt and TIM9 global interrupt                   */
  TIM1_UP_TIM10_IRQn       = 25,    /*!< TIM1 Update Interrupt and TIM10 global interrupt                */
  TIM1_TRG_COM_TIM11_IRQn    = 26,    /*!< TIM1 Trigger and Commutation Interrupt and TIM11 global interrupt */
  TIM8_BRK_TIM12_IRQn       = 43,    /*!< TIM8 Break Interrupt and TIM12 global interrupt                */
  TIM8_UP_TIM13_IRQn       = 44,    /*!< TIM8 Update Interrupt and TIM13 global interrupt                */
  TIM8_TRG_COM_TIM14_IRQn    = 45,    /*!< TIM8 Trigger and Commutation Interrupt and TIM14 global interrupt */
但是在调用时配置如下图：
和以往的改动主要是这一句NVIC_InitStructure.NVIC_IRQChannel=TIM8_TRG_COM_TIM14_IRQn; //
但是为什么定时器不起作用呢，希望各位能帮忙解答一下，非常感谢！！
