Hi 

 
I see that the Luminary examples of interrupt functions do not use
the __irq keyword attribute on the interrupt functions. 

 
Any reason why? (is the __irq not needed when using M3 devices ?
)

The __irq keyword is defined as empty when using Cortex-M3.&lt;/p&gt;

&lt;p&gt;
The reason why it is still in some examples is very simple. The
same source code can be used also for ARM7/9.&lt;/p&gt;

Ok Thanks&lt;/p&gt;

&lt;p&gt;
I just wonder why the TCPNET and CAN example still use the __irq
keyword ...&lt;br /&gt;
(C:\Keil\ARM\Boards\Luminary\ek-lm3s6965\RL\TCPnet\Library\LM3S_EMAC.c
)&lt;br /&gt;
Maybe they forgot to remove it..&lt;/p&gt;

&lt;p&gt;

No function attribute for interrupt function is required because
Cortex-M3 HW takes care of Interrupt Entry/Exit. Therefore interrupt
functions are regular functions and no compiler attributes are
necessary.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: use of __irq with Coretx M3 devices (Luminary)</title><link>https://community.arm.com/thread/49621?ContentTypeID=1</link><pubDate>Sun, 30 Mar 2008 08:08:44 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:b8d22ecd-42b5-43f1-841a-b3f6088ea436</guid><dc:creator>Catcus Blip</dc:creator><description>&lt;p&gt;&lt;p&gt;
it is compiler dependant - realview, GNU, Keil etc.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
