Andy, The records you posted are extended linear address records. Each one specifies the upper 16 bits of the address, creating a full 32 bit address.
Each address prefix will last until a new prefix is declared. :020000040000FA :02 - Bytes in record 0000 - address field - always 0 for this type of record. 04 - Record type Extended Linear Address 0000 - Upper 16 bits of the address FA - Checksum All following records prepend 0000 to their address values: 248F becomes 0000248F :020000040001F9 :02 - Bytes in record 0000 - address field - always 0 for this type of record. 04 - Record type Extended Linear Address 0001 - Upper 16 bits of the address FA - Checksum All following records prepend 0001 to their address values: address 248F becomes 0001248F Keil has a nice page with good descriptions of Intel hex files. http://www.keil.com/support/docs/1584.htm I hope this helps. --Mark Andy Green wrote: > Thanks a lot Maarten, > > I've made sense of the extended address record.
