Thanks @bitboom . I'll review your changes.

@bitboom some nitpicks and one factual error in bitfield offset, otherwise looking good! Please fix at least the invalid OFFSET and we can merge this. Preferably implement enum values for these wide fields, as I see you've already done in some other registers. Thanks!

@berkus Thank you for the detailed review 😄 Most of the feedback has been reflected, and I've added a comment regarding the FIPA field. Let me know if you have any further feedback.
