@(R0, GBR)
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.
Effective address is sum of register Rn and R0
contents.
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.
