I am using the LPC2292, and there is no mention in the LPC2292 errata regarding timer problems. http://www.semiconductors.philips.com/acrobat/erratasheets/2292.pdf Can you maybe point me to the specific errata sheet that describes this ? The idea is to set up a periodic interrupt of x milli-seconds. After the interrupt has been acknowledged, interrupts are enabled again. If an overrun occurs, the interrupt routine will be interrupted, and I can then detect this and take appropriate action as neccesary. Regards Anton Erasmus -- A J Erasmus
