The direct addressing mode consists of two submodes: Direct (short) addressing mode the address is a byte, thus requires only 1 byte after the opcode, but only allows 00 - FF addressing space. Direct (long) addressing mode The address is a word, thus allowing 64 Kbyte addressing space, but requires 2 bytes after the opcode. 11.1.4 Indexed mode (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 indirect addressing mode consists of three submodes: Indexed mode (no offset) There is no offset (no extra byte after the opcode), and allows 00 - FF addressing space. Indexed mode (short) The offset is a byte, thus requires only 1 byte after the opcode and allows 00 - 1FE addressing space. Indexed mode (long) The offset is a word, thus allowing 64 Kbyte addressing space and requires 2 bytes after the opcode. Table 38.
