 Description : Implement I2C I/F using Port #1's No 3(SDA) and No 4(SCL) of 89C51 MCU and Read/Write Serail EEPROM, AT24C02.
               AT24C02 Size : 2K Bits, 256 Byte, 
	       AT24C02 Address Range : 0x00 ~ 0xFF
	       AT24C02 I/F : i2C using SDA and SCL
Note :AT24C02 has Address A2-A0 to address several,but it's not implemented in this source.
And AT24C02 has PAGE(8 BYTE) Writing, but it's not implemented in this source and it's possible to implement using this functions.
