Effective Address Calculation Method

Calculation

Formula

direct

Effective address is register Rn.

(Operand is register Rn contents.)



indirect

@Rn

Effective address is register Rn contents.

indirect with

post-increment

@Rn+

Effective address is register Rn contents. A

constant is added to Rn after instruction

execution: 1 for a byte operand, 2 for a word

operand, 4 for a longword operand.

1/2/4

Rn + 1/2/4

After instruction

execution

Byte: Rn + 1

→

Word: Rn + 2

→

Longword: Rn + 4

→ Rn
