Olin - this is a genuine attempt to understand what is happening here.
I'm NOT just trying to "wind you up".
I'm spending the time and effort in a genuine attempt to try to
improve perspectives - either yours or mine (and other list admins) or
both.

Your reasoned response would be appreciated.

Olin -
            NOT wanting to be "on your case", but this looks from here like=
 a
really non-useful comment and more liable to just make annoyance and
noise than be helpful.

ie  Kris wrote -
"  ... but in the datasheet something weird is written : there is a
note telling this register is available in mode 1 and 2 only.  But in
the description, there is only description for mode 0 ..."

He's saying that either the data sheet is strange or that he doesn't
understand it in some way.
Telling him that the answer is in the datasheet and well explained
seems very marginally useful at best (giving it the benefit of the
doubt).
..
He says he's looked in the datasheet, he's quoting material that
doesn't make sense to him, he's asking for help from people with
practical experience. He says that he's doing a paper design and can't
try it out with the actual hardware.

What more would you expect him to have done?
If you know the answer and decided to reply at all why were you not
more helpful?
If you decided not to be helpful (which is entirely your right) why
did you not just say nothing.

The student/master model "try harder, try harder, try harder, moron,
try ..." has some validity in some circles, perhaps, but doesn't seem
overly useful in this context.

It seems highly unlikely that he would consider an answer which is
effectively of the form "While you say that you have tried to
understand, the answer is in front of your eyes, try harder,
Grasshopper" is in any way useful. The more so because it's possible
that your answer is just flippant and trite and not necessarily useful
- you may effectively be misleading him due to lack of attention on
you part. Given your known skill and experience in such things, odds
are that you are not doing this, but he can't be sure.

Your reasoned and reasonable comment would be useful.
Optionally something like a 'mea culpa, sorry, didn't see it that way,
good point, ..." would be acceptable.
Or better still, a stunningly inspired and lucidly clear technical
explanation (such as you are well known to  be capable of) would be
marvellous :-)
