Hello there!
Does anyone know the values(exactly) for the P.O.R. circuit
on that At89S52?
I have programmed it (at least that it what the flash is telling me),
but I don't get to start my circuit! The logic levels on my ports are
the same as if I weren't using a P.O.R. circuit!
Feel free to reply here or at rellutzu_1981@yahoo.com !
Thank you for your time!
Actually my tests showed that EA had to be tied to VCC, not ALE!
What do you say about this?
Or both need VCC?
