A cyclic redundancy check (CRC) is an error-detecting code used to detect data corruption. This value isn't defined in the hex file, and it doesn't make sense to include it in the checksum either, because the calibration value is programmed into each chip at the factory and can be different for each chip, so if it was included in the checksum, different chips with the same code would have different checksums. This hash can be used to verify the integrity of the data during transmission. A hash value is shown in hexadecimal format, which means that spaces and the case of the letters are not relevant and serve only for easier reading. 4 is regarded as a remarkable and splendid utility that makes it simple to load and print Binary, Intel Hex and Motorola files, which are often used in memory and Microcontroller devices/ICs.
