Subject: Suspended Microcore?
> Has anyone ever used a 240 chip and the suspended Bicore design to
> create a 4 Nv version? Would it work? I'm trying it out, but if someone
> else has tried it, I'd love some input. Also if anone here has worked
> with the circuit, how easy/dificult is it to run it in 1 process mode?
> I've never seen the 240 used with more than 2 Nvs. Also, is it possible

> diagonal Nvs if the thing is in saturation. How will this affect time
