Data Register, D7–D0
Address Register, A7–A0
A twos complement or sign-extended displacement added as part
of the effective address calculation; size is 8 (d
when omitted, assemblers use a value of zero.
Address or data register used as an index register; form is
Xn.SIZE
size) and SCALE is 1, 2, 4, or 8 (index register is 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.
Program Counter
Immediate value of 8, 16, or 32 bits
Effective Address
Use as indirect access to long-word address.
