2.2.7 Address Register Indirect with Index (8-Bit Displacement) Mode
This addressing mode requires one extension word that contains an index register indicator
and an 8-bit displacement. The index register indicator includes size and scale information.
In this mode, the operand is in memory. The operand’s address is the sum of the address
register’s contents; the sign-extended displacement value in the extension word’s low-order
eight bits; and the index register’s sign-extended contents (possibly scaled). The user must
specify the address register, the displacement, and the index register in this mode.
