helllo , all friend
I have just learn ARM7 LPC2148 and I have some problem about VIC when it assigned to IRQ_vector.My problem means, how can I use more than one IRQ interrupt (IRQ vector) at the same time . and the code for it. Some friend tell me After I allow Interrupt sources which I want ,I can assign each ISR_routine functions to VICvectorAddr0,VICvectorAddr1,...etc(example VICvectorAddr0=unsigned(ISR_routine function1)
VICvectorAddr1=unsigned(ISR_routine function2)
) but I don't know how Arm can recognise which ISR_routine function service for which Vector IRQ interrupt-sources.
