You can use extended addresses by adding 80hex to the non-extended

address primitive. With extended addresses, the AAAA field is expanded

from sixteen bits to 32 bits (AAAAAAAA). This allows you to access data

element locations beyond the non–extended limit of 65,535. With extended

addresses, you can access up to 4,294,967,296 locations.
