PICC中使用__EEPROM_DATA()宏指令初始化EEPROM数据存储区，该指令会将写入EEPROM的数据存入HEX文件，然后写入单片机。 用法： #include "pic.h"  //包含头文件 __EEPROM_DATA(0,1,2,3,4,5,6,7); //包含8个数据（不能多也不能少） 该宏可以接受8个字节型的数据，也可以接受用单引号表示的字符，这个宏可以多次调用直到EEPROM写满为止，一般这个宏写在函数定义的外部，我一般是写在__CONFIG 之后，该宏不能在函数运行状态下调用。 PICC中的写法：

// 0x00 - 0x0f    
__EEPROM_DATA (0x55,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
// 0x10 - 0x1f
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);    
// 0x20 - 0x2f
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);        
// 0x30 - 0x3f
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);        
// 0x40 - 0x4f
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);        
// 0x50 - 0x5f
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);        
// 0x60 - 0x6f
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);
__EEPROM_DATA (0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa,0xaa);            
// 0x70 - 0x7f
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);    
// 0x80 - 0x8f
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
// 0x90 - 0x9f
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
// 0xa0 - 0xaf
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
// 0xb0 - 0xbf
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);

__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
// 0xd0 - 0xdf
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
// 0xe0 - 0xef
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
// 0xf0 - 0xff
__EEPROM_DATA (0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00);
