NOTES:
Dn
=
Data Register, D0–D7
An
=
Address Register, A0–A7
d8, d16 =
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.
Xn
=
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 is multiplied by
SCALE); use of SIZE and/or SCALE is optional.
bd
=
A twos-complement base displacement; when present, size can be
16 or 32 bits.
od
=
Outer displacement added as part of effective address calculation
after any memory indirection; use is optional with a size of 16 or 32
bits.
PC
=
Program Counter
<data> =
Immediate value of 8, 16, or 32 bits
( )
=
Effective Address
[ ]
=
Used as indirect address to long-word address.
