Instruction set

ST72324xx-Auto

11.1.5 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

submodes:

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)

Obsolete Product(s) - Obsolete Product(s) 11.1.6

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

space, and requires 1 byte after the opcode.

Indirect indexed (short, long)

This is a combination of indirect and short indexed addressing modes. The operand is

referenced by its memory address, which is defined by the unsigned addition of an index

register value (X or Y) with a pointer value located in memory. The pointer address follows

the opcode.

The indirect indexed addressing mode consists of two submodes:

Indirect indexed (short)

The pointer address is a byte, the pointer size is a byte, thus allowing 00 - 1FE addressing

space, and requires 1 byte after the opcode.

Indirect indexed (long)

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

space, and requires 1 byte after the opcode.
