DS1302时钟1602显示

为什么我程序下载后，1602液晶显示的不是我输进去的数值，而且关掉电源再开还有存储功能，还从刚才断电的地方继续走。
如图所示：

程序如下：
#include
#include"LCD1602.h"
#define uchar unsigned char
#define uint unsigned int
***it TSCLK=P1^0;
***it tiO=P1^1;
***it TEN=P1^2;
uchar Year,Month,Day,Hour,Min,Sec;
void delayms(uint z) //延时函数ms
{
uint x,y;
for(x=z;x>0;x--)
for(y=114;y>0;y--);
}
void Write_1302date(uchar com,uchar dat) //DS1302写数据
{
uchar i;
TEN=0;
TSCLK=0;
TEN=1;
for(i=0;i<8;i--)
{
TSCLK=0;
TIO=com&0x01;
TSCLK=1;
com>>=1;
}
for(i=0;i<8;i--)
{
TSCLK=0;
TIO=dat&0x01;
TSCLK=1;
dat>>=1;
}
}
uchar Read_1302date(uchar com) //DS1302读数据
{
uchar i,dat;
TEN=0;
TSCLK=0;
TEN=1;
for(i=0;i<8;i++)
{
TSCLK=0;
TIO=com&0x01;
TSCLK=1;
com>>=1;
}
for(i=0;i<8;i++)
{
TSCLK=0;
dat>>=1;
if(TIO)    dat|=0x80;    //如果TIO为高电平写1 否则写0
TSCLK=1;
}
return dat;
}
uchar date_BCD(uchar dat)  //数据转BCD
{
uchar dat1,dat2;
dat1=dat/10;
dat2=dat%10;
dat2=dat2+dat1*16;
return dat2;
}
uchar BCD_date(uchar dat)    //BCD转数据
{
uchar dat1,dat2;
dat1=dat/16;
dat2=dat%16;
dat2=dat2+dat1*10;
return dat2;
}
void main()
{
init();
Write_1302date(0x8e,0);//关闭写保护
Write_1302date(0x80,date_BCD(30)); //秒
Write_1302date(0x82,date_BCD(15)); //分
Write_1302date(0x84,date_BCD(5)); //时
Write_1302date(0x86,date_BCD(30)); //日
Write_1302date(0x88,date_BCD(9));  //月
Write_1302date(0x8c,date_BCD(17));;//年
Write_1302date(0x8e,0x80);//开启写保护
while(1)
{
Write_1302date(0x8e,0);//关闭写保护
Sec=BCD_date(Read_1302date(0x81));
Min=BCD_date(Read_1302date(0x83));
Hour=BCD_date(Read_1302date(0x85));
Day=BCD_date(Read_1302date(0x87));
Month=BCD_date(Read_1302date(0x89));
Year=BCD_date(Read_1302date(0x8d));
Write_1302date(0x8e,0x80);//开启写保护
ONE_Write_sfm(7,Year);
ONE_Write_sfm(10,Month);
ONE_Write_sfm(13,Day);
TWO_Write_sfm(6,Hour);
TWO_Write_sfm(9,Min);
TWO_Write_sfm(12,Sec);
}
}

1602.h程序如下：
#define uchar unsigned char
#define uint unsigned int
***it lcden=P3^4;  //使能端
***it lcdrs=P3^5;  //数据命令选择端
***it lcdrw=P3^6;  //读写控制端
***it dula=P2^6;
***it wela=P2^7;
uchar code table3[]="Date:20  -  -  ";

void delay(uint z) //延时函数ms
{

}

{
