† 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.
