请各位高手指点一下（STM8L151K6单片机定时器不能中断）

是否解决:

用的是STM8L151K6单片机
发现定时器不能中断，代码如下
extern @far @interrupt void time2_IRQHandler(void);
struct interrupt_vector const _vectab[] = {
{0x82, (interrupt_handler_t)main}, /* reset */
{0x82, NonHandledInterrupt}, /* trap  */
{0x82, NonHandledInterrupt}, /* irq0  */
{0x82, NonHandledInterrupt}, /* irq1  */
{0x82, NonHandledInterrupt}, /* irq2  */
{0x82, NonHandledInterrupt}, /* irq3  */
{0x82, NonHandledInterrupt}, /* irq4  */
{0x82, NonHandledInterrupt}, /* irq5  */
{0x82, NonHandledInterrupt}, /* irq6  */
{0x82, NonHandledInterrupt}, /* irq7  */
{0x82, NonHandledInterrupt}, /* irq8  */
{0x82, NonHandledInterrupt}, /* irq9  */
{0x82, NonHandledInterrupt}, /* irq10 */
{0x82, NonHandledInterrupt}, /* irq11 */
{0x82, NonHandledInterrupt}, /* irq12 */
{0x82, time2_IRQHandler}, /* irq13 */
{0x82, NonHandledInterrupt}, /* irq14 */
{0x82, NonHandledInterrupt}, /* irq15 */
{0x82, NonHandledInterrupt}, /* irq16 */
{0x82, NonHandledInterrupt}, /* irq17 */
{0x82, NonHandledInterrupt}, /* irq18 */
{0x82, NonHandledInterrupt}, /* irq19 */
{0x82, NonHandledInterrupt}, /* irq20 */
{0x82, NonHandledInterrupt}, /* irq21 */
{0x82, NonHandledInterrupt}, /* irq22 */
{0x82, NonHandledInterrupt}, /* irq23 */
{0x82, NonHandledInterrupt}, /* irq24 */
{0x82, NonHandledInterrupt}, /* irq25 */
{0x82, NonHandledInterrupt}, /* irq26 */
{0x82, NonHandledInterrupt}, /* irq27 */
{0x82, NonHandledInterrupt}, /* irq28 */
{0x82, NonHandledInterrupt}, /* irq29 */
};

@far @interrupt void time2_IRQHandler(void)
{
  RCRST_1;
TIM2_SR1 &= ~0x01; //清除中断标记
  RTC_FLOW_FLAG = 1;

  return;
}

void sys_ini(void)
{
unsigned char i;

CLK_ICKCR |= 0X01; //打开内部HSI时钟
while(!(CLK_ICKCR & 0X02)); //等待内部时钟稳定
CLK_CKDIVR = 0x12; //0x1a; //
CLK_CSSR = 0X00;

TIM2_IER = 0X00; //先禁止中断
TIM2_EGR = 0X01; //允许产生更新事件
TIM2_PSCR = 0X04;
TIM2_ARRH = RTCH_SET; //设置定时
TIM2_ARRL = RTCL_SET;
TIM2_CNTRH = RTCH_SET;
TIM2_CNTRL = RTCL_SET;
TIM2_CR1 |= 0X81; //开启定时器时间初始值
TIM2_IER |= 0X01; //允许更新中断

_asm("rim"); //允许CPU全局中断
}

已经搞了一个星期了，真的要崩溃了。是我的技术太菜了吗?确实是刚接触STM。哎！请高手指点一下啊
extern @far @interrupt void time2_IRQHandler(void);有声明的，这个声明在STM_INTERRUUT_VECTOR.C中
会不会是单片机质量有问题或者烧录器有问题啊，用的是ST-LINK/V2
