新唐RTC不能用查询，要用中断，不然会发生跳变，为什么？难道是芯片的BUS吗？

程序改了，还是查询，没发生跳变，一晚上快半小时，请问什么样时间校准？

int main (void)
{
S_RTC_TIME_DATA_T sInitTime, sReadRTC;

SYS_Init();
UART0_Init();
sInitTime.u32Year    = 2017;
sInitTime.u32Month    = 3;
sInitTime.u32Day       = 10;
sInitTime.u32Hour    = 22;
sInitTime.u32Minute    = 30;
sInitTime.u32Second    = 0;
sInitTime.u32DayOfWeek  = RTC_TUESDAY;
sInitTime.u32TimeScale  = RTC_CLOCK_24;
      printf("\n RTC Time Display Test \n\n");

      while(1){
            RTC_GetDateAndTime(&sReadRTC);
            if(sReadRTC.u32Second!=temp)
            {
                     printf(" %d/%02d/%02d %02d:%02d:%02d\n",
                                 sReadRTC.u32Year, sReadRTC.u32Month, sReadRTC.u32Day, sReadRTC.u32Hour, sReadRTC.u32Minute, sReadRTC.u32Second);
                     temp=sReadRTC.u32Second;

            }
      }
