基于51单片机程序改错

      这个程序用来实现液晶时钟，编译时出" error C193: '/': bad operand type"，请问错在那里啊，怎么该这个错。
程序如下：
      #include <reg52.h>
#include <absacc.h>
#include <intrins.h>

#define uchar unsigned char
#define unit unsigned int

sbit T_CLK = P1^3;

sbit key0 = P3^0;
sbit key1 = P3^1;
sbit key3 = P3^2;
sbit ACC7 = ACC^7;
sbit ACC0 = ACC^0;

uchar datechar[] = {"DATE:"};

uchar data tdata[3] = {0x00,0x00,0x00};

void WriteB(uchar ucDa)
{

for(i=8;i>0;i--)
{

T_CLK = 1;
T_CLK = 0;

}
}

uchar  ReadB(void)
{

只能告诉你是数据类型除了问题

我查了很久都找不到数据类型在那错的。
