AVR-Chat

Me again 
now i ask about ::: 
In-System Reprogrammable Flash Program Memory
The ATmega8535 contains 8K bytes On-chip In-System Reprogrammable Flash
 memory
for program storage. Since all AVR instructions are 16 or 32 bits wide,
 the Flash is
organized as 4K x 16. For software security, the Flash Program memory
 space is
divided into two sections, Boot Program section and Application Program
 section
The operation of Boot Program section and associated Boot Lock
bits for software protection are described in detail in �Boot Loader
 Support � Read-
While-Write Self-Programming
thanks

Is there any reason you're not getting all this data from the data sheet? 
The data sheets are all available from Atmel's website and contain all the 
info you would need.  If it's not in the data sheet, there's most likely 
also an application note that has further data.  Usually 10 minutes of 
looking around the site will yield nore than enough data.

The FIRST thing I do when I want to work with a new part (not just AVR's) 
is download the data sheet if I can find it. Usually just entering the 
part number on Google will come up with it.

Mido -

I don't know what you are asking. The quote you include
seems very clear to me. The details are all in the data
sheet.

And while it kills trees, when starting a new project I print the
possibly 500 page data sheet (double sided) and put it in the project
notebook with other data sheets. I sprinkle it with Post-It(tm) notes.
Make notes in the margins. Highlight things. All sorts of things to
remind myself as to what decisions I made and why. Both for myself for
anyone in the future who may have to pick up the project and support it.

Yes, I often do that, too.  It's not easy flipping pages back and forth, 
or bookmarking them, in a PDF file!

So it's _you_!  I've been wondering who is using all that paper.

[Actually, paper pulp is a commodity that is mostly a _by-product_ of 
the construction industry, which gets the good stuff - or it is made 
from trees that are grown specifically to be harvested for paper - of 
which there is no shortage. The paper industry plants more trees than it 
uses by an order - and that has been so for 100 years. 
http://www.tappi.org/paperu/all_about_paper/paperClips.htm ] If you need 
to feel bad, worry about something else, like asteroids.

Still, I print two-up - as long as my eyes will allow.

I don't feel bad about it at all (says one who parks a Prius in his  
garage next to a Porsche 928S and two KTM dirtbikes).

My dirtbike club rents 5,000 acres from a paper company for our  
members to ride. We get a place to ride. We pay *them* to let us  
police the property, and build and maintain trails which would be  
critical in the event of a fire. Everyone wins. Use more paper!
