Immediate
Immediate instructions have two bytes: The first byte contains the opcode and the second
byte contains the operand value.
Table 78.
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.
