问 //时钟初始化函数
void RTC_Ini(void)
{  
    //PREINT = Fpclk / 32768 - 1;        // 使用内部时钟，设置基准时钟分频器
    //PREFRAC = Fpclk - (Fpclk / 32768) * 32768;
   
    YEAR = 2004;                // 初化年
    MONTH = 11;                // 初化月
    DOM = 1;                // 初化日
   
    CIIR = 0x01;                // 设置秒值的增量产生一次中断
    ILR  = 0x03;
    CCR  = 0x11;                // 启动RTC，使用独立时钟源

    VICIntSelect = 0x00;
    VICVectCntl3 = 0x20 | 13;
    VICVectAddr3 = (int)RTC_Int;
    VICIntEnable |= (1 << 13);
}

请问：在RTC_Int中断中怎么写？

答 1: 我的是这样的，希望能帮助你ILR = ILR;                                                                //清中断
    SysInfo.DayTimePtr.Second = CTIME0&0x3f;
    SysInfo.DayTimePtr.Minute = (CTIME0&0x3f00) >> 8;
    SysInfo.DayTimePtr.Hour = (CTIME0&0x1f0000) >> 16;
    SysInfo.DayTimePtr.Week = (CTIME0&0x7000000) >> 24;
    SysInfo.DayTimePtr.Day = (CTIME1&0x1f);
    SysInfo.DayTimePtr.Month = (CTIME1&0xf00) >> 8;
    SysInfo.DayTimePtr.Year = ((CTIME1&0xfff0000) >> 16)%100;
    
    if(WorkMode == CONTROL && DispEn.DateTime == 1)                            //刷新时间日期
    {
        DispDateTime();
    }
VICVectAddr = 0;                                                        // 通知中断控制器中断结束
