#14212 - Is this correct?
Hi, I'd like to know if the circuit in this pic is right: http://www.robononis.f2s.com/80C390.jpg
I't a basic 80c390 system, with 2 megs of ram and 1 input device (8 switches) and 1 output device(8 leds).
The NV SRAM is accessed through CE0 and CE1, this for allowing the upload of programs via a loader. The 2 simple peripherals are mapped in the 3rd meg zone (accessed with CE2).
My problem is this: the connection of the leds and the switches is right?
Please have a look at the picture and tell me if there's something wrong.
Also, the reset switch is right or must be debounced?
Thanks!
