I am using 89c55 Micorcontroller for my project. It has 20K flash memory. I want to calculate the checksum value in ROM location. I dont know the starting and end address of Flash ROM Memory, is there any bytes alloted in flash memory to store the checksum value? Suggest some links regardings this.... I also gone through the datasheet of 89c55 but they didnt mention the ROM location.
