STM8S103F3P为什么无法进入定时器4中断？

#include "stm8s.h"

main()
{
GPIO_DeInit(GPIOD);
GPIO_Init(GPIOD, GPIO_PIN_4, GPIO_MODE_OUT_PP_LOW_FAST); //关闭LED
GPIO_Init(GPIOD, GPIO_PIN_3, GPIO_MODE_OUT_PP_LOW_FAST);

TIM4->ARR = 0xff; //自动重装数值为 256
TIM4->PSCR = 0x07; //128分频
TIM4->IER = 0x01; //使能溢出中断
TIM4->CR1 = 0x01; //启动定时器
enableInterrupts();  //开启总中断
while (1){
}
}

@near @interrupt void TIM4_UPD_OVF_IRQHandler (void)
{
GPIO_Init(GPIOD, GPIO_PIN_4, GPIO_MODE_OUT_PP_HIGH_FAST); //打开LED

TIM4->SR1 = ~0x01;
return;
}

如上面程式所示。我想通过定时器的方式来点亮LED 但是调试很久依然没有办法进入定时器4中断程式内部。无法点亮LED  芯片是STM8S103F3P

STM8的vector.c设置了吗？

我这里没有那个文件啊？

在其他型号的单片机上可以进入定时器中断唯独在 STM8S103F3P这款单片机上无法进入定时器4 怎么都无法进入

你使用的是IAR软件吗？

不是是STVD

那么你的项目中要有向量表：
