Clarify the request-reply contract between host and device #46

Open bruno-f-cruz opened 2 months ago

bruno-f-cruz commented 2 months ago

This PR addresses issues #26 and #9 by adding clarifying language to the document.

To summarize:

Clarify that for each Write/Read message a reply is expected from the same register
Strongly discourage the use of polymorphic register behavior. All messages from a given register should have the same payload type and size. The "quantity" or "function" of the register should also not be dependent of the message type.
