Instruction set
ST7LITE49M
136/188
Indexed mode (Long)
The offset is a word, thus allowing 64 Kbyte addressing space and requires 2 bytes after the
opcode.
12.1.5
Indirect modes (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 mode (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 mode (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.
12.1.6
Indirect Indexed modes (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 mode (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 mode (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.
