Is it possible to save some measured data from internal RAM to eeprom, when AT89S8252 gets an order to prepare for shutdown?
I mean simply, if my circuit has one trigger pin for program, that it knows it is a time to write latest status to memory and end the program until the trigger is cleared or circuit is just simply reseted and program starts again?

It would be very useful, but is it an option?

I got friday on my mind...;-)
