I am using externel memory eprom for data storage , we couldnt
fetch the data from the externel memory. So it seems the problem is
with the speed of executon. So please help me configure WAIT
STATES.

... you provide a link to the datasheet (at the manufacturers
website, not some datasheet collection site) for both your uC and
your memory. Also, you need to post your clock speed. I take that you
do have a low address latch (which chip).&lt;/p&gt;

&lt;p&gt;

&lt;p&gt;
Why does that seem so?&lt;/p&gt;

&lt;p&gt;
What have you done to rule-out other possibilies - such as coding
errors, hardware design flaws, and/or hardware faults?&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;please help me configure WAIT STATES&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
As already noted, the standard 8051 architecture does not have
configrable wait states; therefore, if your specific chip does have
it, the way to configure them will also be specific to that chip. so
you&amp;#39;re just going to have to study the &lt;b&gt;Datasheet&lt;/b&gt; for the
specific chip.&lt;/p&gt;

HI.&lt;/p&gt;

&lt;p&gt;
u say it is c51 but u do&amp;#39;nt say what device.&lt;/p&gt;

&lt;p&gt;
i have never used a 51 with wait states.&lt;/p&gt;

&lt;p&gt;
Always yo&amp;#39;re freind.&lt;/p&gt;

&lt;p&gt;
Zeusti.&lt;/p&gt;
