sir ,
i want to add to data from the external memory. so i need correct format for this controller
XBYTE[0x1234] = 0x55; XBYTE[0x1245] = 0x11;
how to add this data and save it to another memory
Why not describing the problem you are trying to solve, instead of telling us details such that you want the data transfered through the accumulator?
If you give the picture, people can help solving the problem.
