Thank you @Peter BENSCH ! This is what I was looking for. I was confused on how the checksum was being evaluated but it makes sense now.

Hello @Peter BENSCH . Thank you.My work requires me to provide a serial number for the ECU. I thought of using a serial number like this. Is there any other way to have a serial number from STM8AF52xx ?
