word. Displacements are always sign-extended to 32 bits prior to being used
the sign-extended displacement value in the low-order eight bits of the ex-
tension word, and the sign-extended contents of the index register (possibly
the index register in this mode.
in effective address calculations.
This addressing mode requires one extension word that contains the index
The address of the operand is the sum of the contents of the address register,
scaled). The user must specify the displacement, the address register, and
In the address register indirect with displacement mode, the operand is in
memory. The address of the operand isthe sum of the address in the address
register plus the sign-extended 16-bit displacement integer in the extension
register indicator and an 8-bit displacement. The index register indicator
includes size and scale information. In this mode, the operand is in memory.
