    Default I2C read and write to 24C01 eeprom

    I and difficulty reading and write to the eeprom,the reading instruction I used is

    I2Cread SDA,SCL,$A0,$00,[data1.......data7]
    I2Cwrite SDA,SCL,$A0,$00,[data1......data7]

    all data are define as word variable

    I'm not sure it have written into the memory correctly or not,but the value of data1 can read into data3 and data2 value can read in data5

    I have check with a oscilloscope using I2C analysis,trigger on missing acknowledge signal all data return no acknowledgement
    have I did something wrong?
