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
Effective address is sum of PC and Rn.
