hi! 
i am using AT89S8252 microcontroller in one of my projects, where i
have to store Passwords from user in EEPROM. I am using Keil
Simulation software. I dont know how to access in-built EEPROM in
AT89S8252 in assembly language. when i am using WCON</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Accessing EEPROM of AT89S8252 using Assembly Language</title><link>https://community.arm.com/thread/112543?ContentTypeID=1</link><pubDate>Wed, 27 Dec 2006 10:24:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:aaee3d46-e368-4289-a36f-e48b95e7c71a</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;

It&amp;#39;s an Atmel part, so just go to the Atmel website &lt;a target="" href="http://www.Atmel.com"&gt;&lt;a href="http://www.Atmel.com"&gt;http://www.Atmel.com&lt;/a&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
In the &amp;#39;Search&amp;#39; box, type &amp;quot;AT89S8252&amp;quot;&lt;/p&gt;

&lt;p&gt;
The resulting page shows you the &lt;b&gt;Datasheet&lt;/b&gt;, Errata, and the
&lt;b&gt;AT89S8252 Primer&lt;/b&gt;.&lt;/p&gt;

&lt;p&gt;
The &lt;b&gt;AT89S8252 Primer&lt;/b&gt; contains sample assembler code for
reading &amp;amp; writing the EEPROM.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Accessing EEPROM of AT89S8252 using Assembly Language</title><link>https://community.arm.com/thread/47479?ContentTypeID=1</link><pubDate>Tue, 26 Dec 2006 07:40:49 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:3447b03c-4d95-4eee-9a12-8509eb88b0bb</guid><dc:creator>Luka Karlovic</dc:creator><description>&lt;p&gt;&lt;p&gt;
I&amp;#39;ve had some example code a long time ago, sorry, I can&amp;#39;t find it
now.&lt;/p&gt;

&lt;p&gt;
If register is not defined, define it yourself!&lt;br /&gt;
Download MCU datasheet from atmel.com, open page with memory map, see
the address of WCON and type&lt;br /&gt;
WCON EQU addr&lt;/p&gt;

&lt;p&gt;
That&amp;#39;s it! it will work, I also had to manually define it in my
code.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
