Jayasooriah,

You have to be one on the most annoying, arrogant and pompous people 
I have encountered.  You have created a problem out of nothing, a 
issue you described in you first post as having be discussed 
previously.  You have taken a preposterous position, initially 
demanding that Philips explain themselves and justify their design.  
All information, ideas and discussion that has not been a direct 
challenge has been ignored, or dismissed. You have challenged people 
to dispute your position rather then discuss it. When nobody was 
interested and your attempts to antagonize and bait people back into 
the dispute failed, you twisted the issue and started the name 
calling again. You and you alone have perpetuated the issue. You 
created a bizarre situation where in the end you come in, save the 
day and become the expert.  You have once again defeated the sinister 
Philips empire. You have made a good attempt at drawing all of us 
foolish designers out of the debilitating grip of the evil LPC family.

So Yes!  You are the master of the * spurious interrupts *.  You 
should be tired of everyone draining your energy with their foolish 
questions.  You *should* be regarded as an expert with every piece of 
information and opinion that spews from your person.  The arrogant 
fools should ignore their own practical experience and knowledge of 
embedded systems and rely on the bits and pieces of information you 
have collected in your strange academic pursuits.

This thread did have some useful and very valid information.  It also 
had some solutions, but it takes a fair bit of work to separate these 
things from all the background noise you create.

The last one of these threads that you managed to keep going degraded 
into name calling and then, when there was nothing else to say,  you 
started correcting peoples speling !  How do you get any work 
done ??!!

I am sure that there must be something that you can contribute to 
this group.  The paper you posted may be useful and might be the best 
way for you to approach these "issues" you have.  Perhaps start a 
thread with "I have researched a problem I have  with .... .Does 
anybody else have the same problem? I might be able to offer some 
insight and maybe even some help."

I also recommend that with the more serious problems, you contact the 
board of directors at Philips directly.


Best of luck.

With kindest regards,
Ian Scanlon
