    Hi Can anybody help me in solving the following problem?

    I have interfaced a serial EEPROM M24C08 from ST to I2C0 port of STR710F .

    I have made E2 line of EEPROM =logic 1 and have Left E1, E0 pins unconnected.

    I am transmitting 0xAC as my first address byte ( which includes the

    device select code-1010 ,

    chip enable E2-1

    and as I am writing to Block2 A9=1;A8=0

    R/W~=0). But the device is not responding?

    The STR710F Hardware reference manual states the user to send one header byte ( 11110xx0) where in 1111 corresponds to the device select code of slave connected. I would like to know why the device select code is fixed to 1111 and how does eeprom ( device select code 1010) will understand this and respond to this?
