 		 #38691 - Backup internal RAM
Hello,

A 8052 board counts, accumulates and keeps the production quantity by increasing its internal RAM (4-byte integer of its 256 byte RAM), despite of suddenly main power shutdown. This internal RAM is backup by 3 Volt Lithium battery. I can do similar job with normal static RAM or external RAM, but I do not know how to do it with internal RAM of microcontroller. Thank you for any helps.
