            DCD    TIM5_IRQHandler                ; TIM5
            DCD    TIM6_DAC_IRQHandler             ; TIM6 and DAC1&2 underrun errors

在F407中启动文件所有关于定时器中断服务函数只有这些，F407中有多达14个定时器，为什么中断函数这么少？是因为例程上的启动文件的问题吗？启动文件是否是可以通过在中断向量表中增减中断服务函数而改变其功能？而且高级定时器这些中断服务函数包括TIM6_DAC_IRQHandler的功能不是很明确，希望能有人帮解答，谢谢！
