Hello, 

 
We have a MCB2300 Arm development kit. 
We want to use external interrupts and SD Card together. 
We have noticed that external interrupt pins are shared with SD/MMC
interface. 
We futher noticed that when we try to use external interrupts</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: MCB2300 SD Card Interface</title><link>https://community.arm.com/thread/66562?ContentTypeID=1</link><pubDate>Thu, 05 May 2011 02:29:37 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:f30df322-38f1-4fce-95da-4c72f49e11e3</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
/EINT0 isn&amp;#39;t shared.&lt;/p&gt;

&lt;p&gt;
/EINT1 .. /EINT3 are shared pins so you get a collision.&lt;/p&gt;

But note that you also have access to pin-change interrupts for P0
and P2 giving you some alternatives to /EINT1../EINT3.&lt;/p&gt;
