Effective Address Calculation Method
Effective address is PC with 8-bit displacement
disp added. After disp is zero-extended, it is
multiplied by 2 (word) or 4 (longword), according
to the operand size. With a longword operand,
the lower 2 bits of PC are masked.
Effective address is PC with 8-bit displacement
disp added after being sign-extended and
multiplied by 2.
Effective address is PC with 12-bit displacement
disp added after being sign-extended and
multiplied by 2.
