Effective Addresses Calculation
The effective address is the PC value plus an 8-bit
displacement (disp). disp is zero-extended, is
doubled for a word operation, and is quadrupled for
a longword operation. For a longword operation,
the lowest two bits of the PC are masked.
*: For longword
The effective address is the PC value sign-
extended with an 8-bit displacement (disp),
doubled, and added to the PC.
The effective address is the PC value sign-
extended with a 12-bit displacement (disp),
doubled, and added to the PC.
