Kain Posted May 31, 2006 Report Share Posted May 31, 2006 I am really curious if EPROMs or EEPROMs allow for "don't care" conditions. Any ideas? Quote Link to comment Share on other sites More sharing options...
oldgrandpainmi Posted May 31, 2006 Report Share Posted May 31, 2006 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.oldgrandpainmi Quote Link to comment Share on other sites More sharing options...
Kain Posted June 1, 2006 Author Report Share Posted June 1, 2006 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... :'( Quote Link to comment Share on other sites More sharing options...
