Instruction Set

109/126

Indirect (Short, Long):

The required data byte to do the operation is found by its memory address, located in

memory (pointer).

The pointer address follows the opcode. The indirect addressing mode consists of two sub-

modes:

Indirect (short):

The pointer address is a byte, the pointer size is a byte, thus allowing 00 - FF addressing

space, and requires 1 byte after the opcode.

Indirect (long):

The pointer address is a byte, the pointer size is a word, thus allowing 64Kb addressing

space, and requires 1 byte after the opcode.
