    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.

    Look in the datasheet of the microcontroller.

    My experience has been that a memory location of the programmer's choosing is set aside for containing a checksum value against which the computed checksum is compared.
