I believe there are some on the list that have used the ISD chips before.  For the ISD4002, is there a method to put it in a looping mode? ie....give it an address it will continuously loop till a stop command is given.  I *thought* I saw something that said it was possible, but then going back and looking at the data sheets and app notes couldnt locate that.  Maybe it was some obsure app note I found, but read thru them again.  I've contacted the factory, but no response (surprise huh?)
