Hello all, 
A colleague of mine is dealing with a problem: he seems to be missing
edge triggered interrupts. I checked the code but I
couldn&amp;#226;€™t find long periods during which IEN or for
that matter the respective control registers IE flags are disabled</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: A question about XC167 eletrical properties</title><link>https://community.arm.com/thread/99581?ContentTypeID=1</link><pubDate>Sat, 01 Sep 2007 02:03:08 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:484a976e-ea6b-4a29-90df-3604df00cc57</guid><dc:creator>Sauli Porttila</dc:creator><description>&lt;p&gt;&lt;p&gt;
XC167 User&amp;#39;s Manual Volume 1:&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;An external interrupt signal is safely recognized in two
cases:&lt;br /&gt;
- if it is active for more than 100 ns (async. logic with spike
filter), or&lt;br /&gt;
- if it is active for more than 2 cycles of fSYS (sync. logic).&lt;br /&gt;
The interrupt signal is recognized after whatever condition becomes
true first.&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
You need not worry about losing interrupts due to disabling a
single source or all interrupts globally, the interrupt is still
recognized and remains pending. You may miss a repeated interrupt
though.&lt;/p&gt;

&lt;p&gt;

Hi,&lt;br /&gt;
Sorry - it is a XC167CS.&lt;/p&gt;

&lt;p&gt;
Greetings.&lt;/p&gt;

That information requires the complete name of the used chip - it
isn&amp;#39;t enough to just consider a generic processor family.&lt;/p&gt;
