Effective Address Calculation Method
Effective address is register Rn contents with
4-bit displacement disp added. After disp is
zero-extended, it is multiplied by 1 (byte), 2
(word), or 4 (longword), according to the
operand size.
contents.
Effective address is register GBR contents with
8-bit displacement disp added. After disp is
zero-extended, it is multiplied by 1 (byte), 2
(word), or 4 (longword), according to the
operand size.
Effective address is sum of register GBR and
R0 contents.
