Effective Addresses Calculation
The effective address is the PC value plus an 8-bit
displacement (disp). disp is zero-extended, and
remains the same for a byte operation, is doubled for
a word operation, and is quadrupled for a long word
operation. For a long word operation, the lowest two
bits of the PC are masked.
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.
