I need a CRC-8 bit XFP complient CRC piece of code

Sean Cleary

I need a XFP complient CRC code module. Or I need to validate the one that I got. So any help (pointers to code, pointers to XFP CRC spec, notes on how to validate) would help.

    My table for this poly differs from yours. My table[47] is 0xCD, whereas yours is 0xCB. 0xCB is also in your table[247] where I believe it belongs, but the duplication I think demonstrates that the 0xCB in table[47] is not correct. The feedback table should have unique values throughout, should it not?
