I am using A51 for AT89C51ED2. Am I missing something very basic
or is there no way to declare space specifically in the internal
EEPROM? Do I just declare it as &amp;quot;XDATA&amp;quot; and then use the protocol for
reading and writing in EEPROM when accessing it?</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: EEPROM Data Space</title><link>https://community.arm.com/thread/56083?ContentTypeID=1</link><pubDate>Thu, 14 May 2009 07:10:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:8a46f8f2-f1a6-44fb-8328-5f948ca53b39</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Note that the EEPROM doesn&amp;#39;t work like normal memory. You must
write own code to check busy flag etc.&lt;/p&gt;

&lt;p&gt;
And the address space of the EEPROM is overlapping with normal
XDATA, so you may have to turn off interrupts before banking in the
EEPROM.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
