Hi, I am usingthe LPC936 and for some reason the Internal oscillator is not working right. I have configured it same as i would do for a LPC932...see below. At the beginning of program execution is fine...It sends a pulse about 94msec wide like it is supposed to do. Then, sometime later 2 min, 30 min, it is supposed to send the same pulse, but its width is only 5msec. I have selected a delay function just for this pulse and still does the same thing. Also, I have prepared a RTC using timer zero and it just counts the hours and days very quickly. I use the same program for the LPC932 and it works just fine.
What could be wrong here?

Thanks!
