i2c problem on TMS320F28335 with DAC8574

Hi,

 

I'm trying to connect eZdsp F28335 with DAC8574. This is done by MATLAB Simulink. My problem is: when i use the default slave address register ( 80 ) on i2c lines everything is perfect (I use logic analyzer to monitor what happens on i2c lines), but when I change the address of the slave device (in my case is 76 to 79) on i2c lines nothing happens. Thank you in advance.
