Is this code snippet right?

       integer start = level & edge;
       integer end = ~level & edge;
       integer held = level & ~edge;
       integer unheld = ~(level & edge);

unheld would be true for any bit that had a falling edge, was held high, or was held low. I think that last line should be...

       integer unheld = ~(level | edge);

...or the equivalent...

       integer unheld = ~level & ~edge;
