// If any of these address table definitions ever need to change, it is highly
// desirable to only add new entries, and only add them on to the end of an
// existing address table... this will provide the best compatibility with
// any existing code which may utilize the tables, and which may not be able to 
// be updated to understand a new format (example: bootloader which reads the 
// application address table)
