Hey, actually I do think that describing which hardware configurations the software performs is a Good Thing (TM).
Exactly, "which hardware configurations the software performs", XSELNAND is not performed in software, this is just a pin you wire high or low on your board. That's why I said we might not need to comment upon it. That's how I interpreted the datasheet anyway.
I don;t think how this would make a difference. Even if the signal is defined by the hardware dsign - the very moment I am referencing this signal in any piece of software I should explain it so the reader of the code understands what I'm doing.
Using meaningful names instead of magic numbers is a minimum to do.
Best regards,
Wolfgang Denk
