PICers,
Following on something that was mentioned the other day, if someone could please clarify something for me .....

The RB0 interrupt in the 16F84 is edge triggered and, looking at the data sheet, u can set it to go off on a rising/falling edge with b6 in the OPTION register.

OK, so that means you can leave RB0 held HIGH then trip the interrupt when it goes low?

I sorta had the mental picture that u have to keep RB0 low then trip the interrupt on the leading or falling edge of a (+) pulse. But this is not so?

ie You can fire the interrupt on the rising/falling edge of a (-) going pulse on RB0, is wot I'm getting at?

Thankz - Debbie :)
