新手求助。我用的是STM32F103ZG，电路图中用到了TIM9测PWM输入的高电平，但是在固件库V3.5中定义TIM9的中断优先级时，运行出错

2019-07-21 03:22发布

main中：       //确定定时器9溢出优先级
      NVIC_InitStructure.NVIC_IRQChannel =TIM9_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2; //先占级（待定）
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;//次占级（待定）
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
出错信息：
..Usermain.c(555): error:  #20: identifier "TIM9_IRQn" is undefined

所用芯片：STM32F103ZG。

而且在startup_stm32f10x_hd.s中找不到为TIM9开辟中断地址的语句。请问是不是TIM9的中断不能用？该如何处理？
