EEPROM này của Microchip phải không bồ
Mình tìm được đoạn code này bồ thử xem sao nhe.

unsigned char read_ext_eeprom(unsigned long address)
{
    unsigned char command;
    unsigned char data;

    IdleI2C1();

    if (address > 65535)
        command = 0xa8;
    else
        command = 0xa0;

    StartI2C1();
    status = MasterWriteI2C1(command);
    while(I2C1STATbits.TBF); //Wait till address is transmitted
    AckI2C1();
    IdleI2C1();

    MasterWriteI2C1(address >> 8);
    while(I2C1STATbits.TBF); //Wait till address is transmitted
    AckI2C1();
    IdleI2C1();

    MasterWriteI2C1(address);
    while(I2C1STATbits.TBF); //Wait till address is transmitted
    AckI2C1();
    IdleI2C1();

    StartI2C1();
    MasterWriteI2C1(command | 0x01);
    while(I2C1STATbits.TBF); //Wait till address is transmitted
    AckI2C1();

    IdleI2C1();

    data = MasterReadI2C1();
    NotAckI2C1();

    StopI2C1();

    return data;
}
