I'm using P89C51RD+ which has 64kb Flash. I am using the remaining memory of the Flash after the code.When the memory is full I want to tranfer the data to the pc. My problem is where to start to look for the memory data in order to stabilish the initail addrees for the transfer.I want to design a solution that allows the program by itself distinguishes the code data from the memory data.Is there any pattern that charcaterizes the end of the code memory?
