EPROMs and "Don't Cares"

Recommended Posts

Kain,

In short, No.

(over simplified-----) Basicly, regardless of type, ROM's are just that- Read Only Memory.  You supply an address, and the data is what you have programmed into that address.  If there is a point in the rom that you do not want to use, or "don't care" what it has, don't use it.  There MAY be packages where there is a pin or two that may have a "don't care" situation, I think durring the programming of the EEPROM there is an input or two that sit's in a "don't care" situation, but that condition does not exist durring normal operation.

Ok that sounds bad now. So virtually I have to describe all situations where don't cares will normally simplify the situation... That just made my code close to 4000 lines...  :'(
