MOTOROLA
The memory indirect addressing modes use a long-word pointer in memory
to access an operand. Any of the modes previously described can be used
to address the memory pointer. Because the base and index registers can
both be suppressed, the displacement acts as an absolute address, providing
indirect absolute memory addressing (refer to Figure 2-8).
NOTE: Regardless of array structure, software increments index by the
A 6 = 1 ~
appropriate amount to point to next record.
