Kain Posted May 31, 2006 Report Posted May 31, 2006 I am really curious if EPROMs or EEPROMs allow for "don't care" conditions. Any ideas? Quote
oldgrandpainmi Posted May 31, 2006 Report 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
Kain Posted June 1, 2006 Author Report 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
