Dear All, 
I am using Silabs 8051F340 processor to which a temperature and
humidity sensor(sensirion) is interfaced. 
This sensor is interfaced using I2C like(2 wire serial) protocol.
Code works fine when it gets power from debug adapter.(Background</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Code works only with Debug  Adapter</title><link>https://community.arm.com/thread/114890?ContentTypeID=1</link><pubDate>Thu, 07 May 2009 21:33:57 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:732150eb-cc35-497f-af63-350e47e35b6f</guid><dc:creator>Ameya Hardikar</dc:creator><description>&lt;p&gt;&lt;p&gt;

I am giving 5V input to REGIN pin; which accepts 5V. chip has
internal regulator which convert it to 3V3.&lt;/p&gt;

oh, this is one of those with a regulator built in, but
&lt;b&gt;still&lt;/b&gt; a 3V3 part. Well then the mystery maybe is solved. If
the regulator is disabled it will give this exact effect since the
pod connect 3V3 to the chip.&lt;/p&gt;

&lt;i&gt;the SILabs parts are 3V3 parts and if it still works after
being connected to 5V you are VERY lucky.&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Wrong as usual, I&amp;#39;m afraid.&lt;/p&gt;

&lt;i&gt;I am using Silabs 8051F340 processor ... connected to
independent power supply of 5V&lt;/i&gt;&lt;br /&gt;
the SILabs parts are 3V3 parts and if it still works after being
connected to 5V you are VERY lucky. Even if it &amp;#39;works&amp;#39;, I would
replace it, it will be severely weakened.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;I checked my RESET circuit as well; it&amp;#39;s okay.&lt;/i&gt;&lt;br /&gt;
How do you know?&lt;br /&gt;
do you have the reset pulled up by ~1k and no cap there?&lt;/p&gt;

&lt;p&gt;
