hi ..
 

 

by this way :

 

 

 

   unsigned int data,addtion,add ;

   unsigned char upper,lower;

 

/* write operation*/

   lower = data%100;  // lower byte
   upper = data/100;  // upper byte  
 
 
/* read operation*/
 
   addtion = lower;
   add = upper<<8;
   add = add | addtion;
   
   i write eeprom by this way …but when i perform read operation the value will changed ..
   but result is changed …
  for that what i have to do ..??
