hi friends, i'm making a counter using 89c51 & 7-segment displays. i want to save the last value in eeprom on a power failure. i have the write routines required to write to eeprom. but i don't no how to create a interrupt on power failue. my idea is to have a big condensor 2200 uC and use it's power to write to eeprom. i'm using 24c02 eeprom.
thanks a lot
