The postindexed indirect mode (see Figure 2-12) uses the contents of An as
an index to the pointer list at the displacement. Register Xn is used as an
index to the structure of data items located at the address specified by the
pointer. Figure 2-13 shows the preindexed indirect addressing with outer
displacement mode.
