2.4.8 A d d r e s s Register Indirect w i t h I n d e x (Base D i s p l a c e m e n t ) M o d e
MOTOROLA
This addressing mode requires an index register indicator and an optional
includes size and scaling information. The operand is in memory. The address
of the operand is the sum of the contents of the address register, the scaled
contents of the sign-extended index register, and the base displacement.
In this mode, the address register, the index register, and the displacement
are all optional. If none is specified, the effective address is zero. This mode
provides a data register indirect address when no address register is specified
and the index register is a data register (Dn).
