 What is the difference between interrupt Raw status register
and interrupt status register on LPC3250?

Thank you. i got the difference.&lt;/p&gt;

The normal approach would be to fully initialise the source of the
interrupt before enabling the interrupt. That initialisation would
clear (release) any old pending interrupt.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Difference B/W RAW Status Reg and Status Reg on LPC3250</title><link>https://community.arm.com/thread/78551?ContentTypeID=1</link><pubDate>Wed, 11 Aug 2010 02:11:03 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:1f3d4b26-f7ea-439d-9104-60224617d505</guid><dc:creator>eswar g</dc:creator><description>&lt;p&gt;&lt;p&gt;
yes. i got this point from user manual. but my question is are we
need to check this register before enable interrupt on ER register.
Is this make any difference if we won&amp;#39;t check?&lt;br /&gt;
For interrupt on GPIO i used RSR interrupt to acknowledge. but in
timer we have TnIR to acknoledge. how can we use this registar?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Difference B/W RAW Status Reg and Status Reg on LPC3250</title><link>https://community.arm.com/thread/104161?ContentTypeID=1</link><pubDate>Wed, 11 Aug 2010 02:03:54 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:b18f22bc-bc74-46ea-b258-e951901cceed</guid><dc:creator>Tamir Michael</dc:creator><description>&lt;p&gt;&lt;p&gt;
The raw interrupt is unfiltered/unmasked; the status is.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Difference B/W RAW Status Reg and Status Reg on LPC3250</title><link>https://community.arm.com/thread/58532?ContentTypeID=1</link><pubDate>Wed, 11 Aug 2010 02:03:40 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:7487ab9f-603a-4b12-859a-6517d01986b9</guid><dc:creator>Non Keil Related</dc:creator><description>&lt;p&gt;&lt;p&gt;
If you refer to the LPC32x0 user manual chapter #5 it states for
the Raw Status Register:&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;... RSR shows which interrupt sources are active before being
masked by the ER.&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
whereas it states for the Interrupt status Register:&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;... Status Registers provide information on which interrupts
are actually pending, after being masked by the corresponding Enable
Register&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Is there something wrong with your copy of the user manual?&lt;/p&gt;

I studied the manual i didn&amp;#39;t get. it seems both are similar. but
there is something difference can you please clear my confession?&lt;br /&gt;
Thanks&lt;br /&gt;

Try the user manual!&lt;/p&gt;
