d8, d16 =
Data register, D0-D7
Address register, A0-A7
A twos-complement or sign-extended displacement; added as part of the effective address calculation;
size is 8 (d8) or 16 (d16) bits; when omitted, assemblers use a value of zero.
Address or data register used as an index register; form is Xn, SIZE*SCALE, where SIZE is W or L
(indicates index register size) and SCALE is 1, 2, 4 or 8 (index register os multiplied by SCALE); use of
SIZE and or SCALE is optional.
A twos-complement base displacement; when present, size can be 16 or 32 bits.
Outer displacement added as part of effective address calculation after any memory indirection; use is
optional with a size of 16 or 32 bits.
Immediate value of 8, 16 or 32 bits.
Used as indirect address to long-word address.
