NOTES:
1. Where d is direction, left or right.
2. Available only on the MC68040.
3. Where r is rounding precision, single or double precision.
4. List refers to register.
5. List refers to control registers only.
6. Available only on the MC68040V and MC68EC040V.
7. MOVE16 (ax)+,(ay)+ is functionally the same as MOVE16 (ax),(ay)+ when ax = ay. The address register is only
incremented once, and the line is copied over itself rather than to the next line.
8. Not available for the MC68EC040 or MC68EC040V.
