请问：在RTC_Int中断中怎么写？

//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);
}

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
