MOTOROLA
2.4.10 Memory Indirect Preindexed Mode
The processor accesses a long word at this address and adds the outer
displacement to yield the effective address. Both displacements and the index
OUTER DISPLACEMENT: [
EFFECThfE ADDRESS:
NUMBER OF EXTENSION WORDS:
In this mode, the operand and its address are in memory. The processor
calculates an intermediate indirect memory address using the base register
(An), a base displacement (bd), and the index operand (Xn.SIZE * SCALE).
register contents are sign-extended to 32 bits.
When a displacement is omitted or an element is suppressed, its value is
taken as zero in the effective address calculation.
ASSEMBLER SYNTAX:
ADDRESS REGISTER:
BASE DISPLACEMENT: I
SCALE:
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.
