Effective Address Calculation

Equation

The effective address is register Rn. (The operand

is the contents of register Rn.)

—

The effective address is the contents of register Rn.

with post-

increment

@Rn+

The effective address is the contents of register Rn.

A constant is added to the contents of Rn after the

instruction is executed. 1 is added for a byte

operation, 2 for a word operation, and 4 for a

longword operation.

1/2/4

Rn + 1/2/4

(After

instruction

execution)

Byte:

Rn + 1

→ Rn

Word:

Rn + 2

→ Rn

Longword:

Rn + 4

→ Rn

with pre-

decrement

@-Rn

The effective address is the value obtained by

subtracting a constant from Rn. 1 is subtracted for

a byte operation, 2 for a word operation, and 4 for

a longword operation.

1/2/4

Rn – 1/2/4

–

Rn – 1/2/4

Byte:

Rn – 1

→ Rn

Word:

Rn – 2

→ Rn

Longword:

Rn – 4

→ Rn

(Instruction is

executed with

Rn after this

calculation)
