NOTES:

1. Where d is direction, left or right.

2. Where r is rounding precision, single or double precision.

3. List refers to register.

4. List refers to control registers only.

5. 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.
