Hello, 

 
The user manual of the LPC1114 is clear about how to wake up the
chip from deep sleep: I use IO pin 0.6 which induces an interrupt.
The trouble is that this interrupt keeps on coming and the controller
never returns to the main loop unless</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: LPC1114 deep sleep wakeup procedure</title><link>https://community.arm.com/thread/105493?ContentTypeID=1</link><pubDate>Fri, 18 Nov 2011 01:06:50 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:91354c68-b318-41f8-b0ef-15f7d63f2d97</guid><dc:creator>Tamiryan Michael</dc:creator><description>&lt;p&gt;&lt;p&gt;
Ah, I found a NXP sample that does that same so I am probably
doing the right thing!&lt;/p&gt;

Hello Per,&lt;/p&gt;

&lt;p&gt;
It&amp;#39;s a short pulse (associated with a button - later, there will
be a signal coming in from an external RTC as well). The ISR is
currently empty - apart from identifying the interrupt source and
clearing the startup logic.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: LPC1114 deep sleep wakeup procedure</title><link>https://community.arm.com/thread/67074?ContentTypeID=1</link><pubDate>Fri, 18 Nov 2011 00:42:51 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:225c7435-080c-471b-9496-acd9d945f144</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
I guess it&amp;#39;s a level-trigged interrupt, since edge-trigged
interrupts would normally expect a working clock for sampling of the
signal.&lt;/p&gt;

&lt;p&gt;
But what stimuli do you give on the pin - constant signal or just
a short pulse or what?&lt;br /&gt;
And what does your processor do in the interrupt handler for that
interrupt?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
