stm32 定时器中断~~~着急中

基于库函数v3.5和keil4编程，
已经#include "stm32f10x_it.h"
#include "stm32f10x.h"
其他无误程序省略，
void NVIC_Config(){
NVIC_InitTypeDef NVIC_InitStructure;
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);

NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn ;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority=0 ;
NVIC_InitStructure.NVIC_IRQChannelSubPriority=1 ;
NVIC_InitStructure.NVIC_IRQChannelCmd=ENABLE;
NVIC_Init(&NVIC_InitStructure);
}

中断向量配置如上，其中这一句
NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn ;
改成 NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn ;
NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn ;
均无错

但改成 NVIC_InitStructure.NVIC_IRQChannel = TIM1_IRQn ;
NVIC_InitStructure.NVIC_IRQChannel = TIM5_IRQn ;
NVIC_InitStructure.NVIC_IRQChannel = TIM6_IRQn ;
NVIC_InitStructure.NVIC_IRQChannel = TIM7_IRQn ;
NVIC_InitStructure.NVIC_IRQChannel = TIM8_IRQn ;
都会报编译错误..\User\main.c(32): error: #20: identifier "TIM6_IRQn" is undefined

求好心人帮忙啊，我很想知道到底为什么

打开103的启动文件starup_stm32f10x_md.s，
DCD TIM1_BRK_IRQHandler ; TIM1 Break
DCD TIM1_UP_IRQHandler ; TIM1 Update
DCD TIM1_TRG_COM_IRQHandler ; TIM1 Trigger and Commutation
DCD TIM1_CC_IRQHandler ; TIM1 Capture Compare
DCD TIM2_IRQHandler ; TIM2
DCD TIM3_IRQHandler ; TIM3
DCD TIM4_IRQHandler ; TIM4
这里面只有TIM1-TIM4的定时器中断事件，TIM6是没有中断响应这个功能的。

上面的 NVIC中断事件，要从starup_stm32f10x_md.s这里面找的，不能自己定义这上面没有的中断事件。
如果对你有帮助的话，给分吧。。。
