简单RTC应用，获取RTC时间，以及设置时间

void RTC_Ctrl_Set(U8 enable)  //bit位使能
{
    if (FALSE == enable)
    {
        RTCCON &= ~(1 << 0);
    }        
    else
    {
        RTCCON |= (1 << 0);
    }
}

void Get_RTC_Time(RTC_Time_Typedef *time)
{//获取RTC时钟的各个部分
    time->second = BCDSEC;
    time->minute = BCDMIN;
    time->hour = BCDHOUR;
    time->date = BCDDATE;  //星期
    time->day = BCDDAY;
    time->month = BCDMON;
    time->year = BCDYEAR; 
}

void Set_RTC_Time(RTC_Time_Typedef time)
{//设置RTC时间
    RTC_Ctrl_Set(TRUE);

    BCDSEC = time.second;
    BCDMIN = time.minute;
    BCDHOUR = time.hour;
    BCDDATE = time.date;  //ÐÇÆÚ
    BCDDAY = time.day;
    BCDMON = time.month;
    BCDYEAR = time.year;

    RTC_Ctrl_Set(FALSE);
}
