There are a few settings in my application that need to be remembered after a reset or power loss.  From what I have read so far I need to add external memory, right?  I think there could be 30 bytes max I need to remember.  I wish the program could read bytes from the data table and then save back those bytes that changed.  This is not able to be done, right?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

The parameters written to the external memory could be updated frequently and the data must be remembered on power lost.  No battery backup in this application.<o:p></o:p>
