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.
