hi everybody...

I want know if there is a way to declare the priority of an interrupt in the PIC 18F's.

As far as i know the directive #priority only tells the order that the interrupts will be implemented. So, if an int_ext1 occurs while the pic process the int_ext2 nothing will happen, but I think the PIC18F has two types of priorities, so in the example above I could stop the execution of the int_ext2 and run the int_ext1 (if I put them in the right interrupt vectors)


thanks!!

If you search this forum using the words "high" and "priority" you will find a great deal on the subject including examples.
