关于stm8s105c6 tim1外部时钟源模式2 对外部脉冲计数问题
#include "stm8s.h"#include "stm8s_tim1.h"

void TIM1_Init(void)

}
FLASH_Lock(FLASH_MEMTYPE_DATA);
TIM1_ETRClockMode2Config(TIM1_EXTTRGPSC_DIV2, TIM1_EXTTRGPOLARITY_INVERTED, 0x00);
TIM1_Cmd(ENABLE);
}
u8 COUN1=0;
int main(void)
{
while(1)
{
COUN1=TIM1->CNTRH;
}
}
调用库函数，这个程序能实现这个功能吗？

考虑溢出吗:D
