Hi all,

I have always used, when needed, external level triggered interrupts.

With this I mean I have never used level triggered interrupt besides the typical single step operation.

So I would like to know something about the applications in which you have used External Level Triggered interrupts.

With a brief description of your projects I can figure out what this kind of interrupts are useful for and maybe with your help I will be able to attack future 8052 problems with other point of view.

I know how External Level trigg. interrupts work, that is not the question, simply I would like to know some practical cases in wich they are useful.

Best Regards.
