 <b>*</b> Multiplications are fully supported by the pipeline (in terms of timing, wires and registers). However, the multiplication module itself is null-defined in the ALU, and always returns zero for now. It will be defined and plugged into the ALU in a future version of pAVR. <br>
 <b>**</b> Italicized instructions are currently not implemented in pAVR. <br>
