CRC funcs

[william.ferguson.au]

\rom\crc.h lists a number of CRC funcs and provides the polys used for them.

What are the other CRC initialisation values used for each of the funcs? Ie

• width
• init
• refin
• refout
• xorout

It would make it useful when trying to match CRCs calculated on other systems.

Also it mentions that "we had added a `~` at the beginning and the end of the functions", but I can't understand what it is talking about. What does it mean?

And finally, why is there a crc8_le() and crc8_be()?
Why would a crc8 algorithm care about byte order, since it operates over a stream of single bytes?
