Take a look at Samples/RestartVars/BatteryRAM/bbvars.c for an example of how to use battery-backed RAM for data storage.
For long-term storage (that’s retained even without the backup battery), you can make use of the UserBlock. Look at Samples/UserBock/userblock_sample.c for an example of those APIs.
