*Note: These instructions have an identical set of addressing modes, which are encoded for brevity. The
first opcode nibble is found in the instruction set table above. The second nibble is expressed symbolically
by a ‘[ ]’ in this table, and its value is found in the following table to the left of the applicable addressing
mode pair. For example, the opcode of an ADC instruction using the addressing modes r (destination)
and Ir (source) is 13.
