Notes: 1. This instruction can specify D8-D15 as operands by using a prefix.
2. Register pair order can be reversed for clarity because the order of operation is not
important for add operations.
3. The JJJJJ encoding does not include the pairs: D1,D1; D3,D3; D5,D5; D7,D7. These are
covered in the jj encoding.
