Instruction set
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)
OObbssoolleettee PPrroodduucctt((ss)) -- OObbssoolleettee PPrroodduucctt((ss)) 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.
