The opcode quadrants are: <span style="background-color: #ff6666;">'''Control instructions'''</span>, <span style="background-color: #66ff66;">'''ALU instructions'''</span>, <span style="background-color: #6666ff;">'''Read-Modify-Write instructions'''</span>. '''Illegal instructions'''. The opcodes in bold are unstable.
