Note: Calculation of key sum check data

Hard codes (hexadecimal number) at the position (excluding feed key) where there is an input data contact are added. However, the end key (TL) is not added.

This data to which hard codes have been added is converted into a decimal number value, which will become the sum check data that will be entered when DIAG is started.
