† 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.
