You have two possabilities here:

(Ax,Dy) or 0(Ax, Dy) means Ax + lower 16 bits of Dy sign-extended to 32
bits.
d(Ax,Dy) means Ax + d (8 bits) + lower 8 bits of Dy sign-extended to 32
bits.

AFAIK you can't set Dy in the first case to only use 8 bits, but I wouldn't
mind being proved wrong since it would be useful... :o)
