I seem to have a problem that has me stumped...this is the scenario...if anyone can help me it would be appreciated greatfully...thanks... I have a 16c84 that is storing data in eeprom and then reading it back = for the purpose of the program...this side of things is working great... The problem is that when l dissconnect the power from the input of the regulator l loose all eeprom data...BUT...when l dissconnect power from = the output of the regulator l maintain eeprom memory... Strange l think, but l am sure the problem must be trivial but l cannot = for the life of me seem to figure out what is going on... PLEASE HELP...if just for my sanity...
