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.
Erik he is right NXP moved your links.
In short the chip does not know about checksums or CRCs. You can code them. The code starts at 0. The end is more work. You put the checksum where you want it. I would suggest the end of ROM. You can read the code with a C pointer qualified as "code"
No, they haven't - fortunately!
Erik just managed to copy some "mangled" links!
