hi 

 
I am using AT89C51 for digital clock and some other purpose, I
want to reset circuit at startup, I mean when I turn on the circuit,
at first time “reset circuit” send the one pulse for an
XXn sec to reset pin of 89c51 to reset the microcontroller</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Reset</title><link>https://community.arm.com/thread/66374?ContentTypeID=1</link><pubDate>Thu, 10 Mar 2011 04:30:47 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:31e4e990-0262-46a7-b77c-c25516eddfbf</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
So why did you select the &amp;#39;MCU Architecture/Product&amp;#39; as &amp;#39;None&amp;#39;
??&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I want to reset circuit at startup, I mean when I turn on the
circuit&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Read the chip &lt;b&gt;Datasheet&lt;/b&gt; for its reset requirements.&lt;/p&gt;

&lt;p&gt;
See: &lt;a href="http://www.8052.com/faqs/119931"&gt;www.8052.com/.../119931&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
Google for &amp;#39;Reset Generator&amp;#39; and &amp;#39;Supervisor&amp;#39; and similar
terms.&lt;/p&gt;

&lt;p&gt;
Look at companies like Maxim, TI, &lt;i&gt;et al...&lt;/i&gt;&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
