Re:add user interrupts on future device

Yes,I confirm that user interrupts in MCUs is really useful.No matter how designers use the user interrupts,for example,driving 'user task' or driving peripherals,user interrupts benefit the realtime ability,program simplicity,especially,with the Cortex-M3 NVIC.
Traditional OS are not the only solution(for example,no OSs,or,state machines mothod),especially for most little,deeply embeded use.Most of Luminary MCUs is for this market.So,I think it's a good,new idea for Luminary.
I hope to know if it is a good or bad idea.
thanks,
