Calculation Formula
PC-relative with @(disp:8,
displacement PC)
Effective address is PC with 8-bit displacement disp Word: PC + disp × 2
added. After disp is zero-extended, it is multiplied _Longword:
by 2 (word) or 4 (longword), according to the
PC&H'FFFFFFFC
operand size. With a longword operand, the lower 2 _{+ disp × 4}
bits of PC are masked.
