 		 #122163 - Interupt question......
Quick question....I am not looking for any code or anything so please be nice...LOL :-) Is it possible to detect zero crossing (positive going only) on and interupt then start a timer and perform a function after a certain amout of time ?

Oh yeah I am using an 80C320 and programming in assembler.


Thanks,

Dave
