There are plenty of pages on the interwebs discussing CRC code - it's not specific to particular hardware platforms!

You may have to do the conversion to assembler yourself...

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

the Cosmic compiler for stm8 includes the possibility to use the CCITT CRC: you may use it directly or take a look at the assembler code of the verification routine in order to get an idea of how to implement it.
