Dear David and Murray,

I am presently getting a reply from the eeprom(or i think i am) but it is incorrect. I am writing a 0x11h and getting 0xFFh in reply. Another thing is that this write and read loop should be infinite but in my hardware i can write once and then read, after that the program stops. as David said i corrected the address. I made some additions to the program by sending A unique character after each command to my PC and the reply i get each time, just to check where does my program get stuck

11

FF//here should be 11 instead
11
13
...then nothing after that

cannot think of any particular reason for this !!
