Instruction set

11.1.2

Immediate

Immediate instructions have two bytes: The first byte contains the opcode and the second

byte contains the operand value.

Direct

In Direct instructions, the operands are referenced by their memory address. The direct

addressing mode consists of two submodes:

Direct (short)

The address is a byte, thus requiring only one byte after the opcode, but only allows

00 - FF addressing space.

Direct (long)

The address is a word, thus allowing 64 Kbyte addressing space, but requires 2 bytes after

the opcode.

Indexed (no offset, short, long)

In this mode, the operand is referenced by its memory address, which is defined by the

unsigned addition of an index register (X or Y) with an offset.

The indexed addressing mode consists of three submodes:

Indexed (no offset)

There is no offset, (no extra byte after the opcode), and it allows 00 - FF addressing space.

Indexed (short)

The offset is a byte, thus requiring only one byte after the opcode and allows 00 - 1FE

addressing space.

Indexed (long)

The offset is a word, thus allowing 64 Kbyte addressing space and requires 2 bytes after the

opcode.
