Hi Friends,

Our 8052 supports two types of external interrupts.
1. Low level triggered.
2. Edge triggered [ High to low transition ].

Is it possible to get interrupts on both the transitions i.e. High to lo and low to high both. Is there any trick to do this. Because I have come across lots of application where this thing was really needed but at last I had to use polling instead of interrupts.

Thanks for reading my post.
