Effective Address Calculation Method
Effective address is register Rn.
(Operand is register Rn contents.)
Effective address is register Rn contents.
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.
Effective address is register Rn contents,
decremented by a constant beforehand: 1 for a
byte operand, 2 for a word operand, 4 for a
longword operand.
