PIC16F877A中的EEPROM错误

海都。我用C语言编写了一个简单的内部EEPROM程序，使用MPLAB和高技术C编译器。在PIC16F877 A中，EEPROM为256字节。这是一个简单的程序来存储一些值在寄存器和检查出来。如果它是正确的眨眼LED。但是错误发生了…我收到的错误是“下列内存区域未能正确编程：EdAdA内存地址：0000000 2预期值：00000000接收值：000000 FF编程失败”，虽然我收到错误，但输出正确。我不明白。在地址二中存储0（零）是错误的吗？有人给我解释一下…我在这里附上下面的源代码…

               Hai all. I wrote a simple program for internal EEPROM in C language using MPLAB with HI-TECH C compiler.  In PIC16F877A EEPROM is 256 bytes. It's a simple program to store some value in Register & check it out .. If it's correct blink Led. But the error occurred....
             The error which i received is
                  "The following memory regions failed to program correctly:
                   EEData Memory Address: 00000002 Expected Value: 00000000
                   Received Value: 000000ff Programming failed"
        Though i received the error but the output came correctly.. I don't understand. Is it anything wrong to store 0 (Zero) in address two. Anyone give me the explanation to me..... I here attach the source code below.....


#include
__CONFIG(0x3F3A);
#define _XTAL_FREQ 20000000
int a;
void main()
{
PORTD=0x00;
TRISD=0x00;
eeprom_write(2,0);
a=eeprom_read(2);
while(1)
{
if(a==0)
{
RD0=1;
}
else
{
RD0=0;
}
}
}
