Table 49.
Immediate instructions
Immediate instructions have two bytes, the first byte contains the opcode, the second byte
contains the operand value.
Table 50.
Direct
In Direct instructions, the operands are referenced by their memory address.
The direct addressing mode consists of two sub-modes:
Direct (short)
The address is a byte, thus requires 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 indirect addressing mode consists of three sub-modes:
Indexed (No Offset)
There is no offset, (no extra byte after the opcode), and allows 00 - FF addressing space.
