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-ex-
tended limit of 65,535. With extended addresses, you can access up to 4,294,967,296 loca-
tions.
