 		 #160847 - Non-Volatile Storage
Responding to: ???'s previous message
Of course it is possible - lots of things do it, don't they?!

Whether your particulat chip allows you to do it in CODE memory is another question.

Whether CODE memory is an appropriate place to store it is yet another question.

What about Kiran V. Sutar's suggestion of using an external EEPROM?

For other options, the search keywords you need are "non volatile storage"...
