problem I2C on ML507

hello,

I work on ML507 board. I try to connect my board with the device PCF8591 through IIC
so that i can receive data from this device. So firstly, I send the address of this device but it didn't work.
I see nothing on the oscilloscope ( on SCL and SDA pin),
I connected these two pins with resistors pull up.
Can someone help me?
Thanks in advance.
Regards,

A common problem seems to be that people use the _I, _O, and _T signals individually.  If you are not already using the _IO version of the SDA and SCL pins you might want to try that first.
