2.4.9 Memory Indirect Postindexed Mode
When a displacement is omitted or an element is suppressed, its value is
taken as zero in the effective address calculation.
address and adds the index operand (Xn.SIZE*SCALE) and the outer dis-
placement to yield the effective address. Both displacements and the index
In the syntax for this mode, brackets enclose the values used to calculate the
intermediate memory address. All four user-specified values are optional.
Both the base and outer displacements may be null, word, or long word.
In this mode, the operand and its address are in memory. The processor
calculates an intermediate indirect memory address using the base register
(An) and base displacement (bd). The processor accesses a long word at this
register contents are sign-extended to 32 bits.
