Notes
1. Single task every field; OFIDC = 0; subaddress 90H at 40H; TEB[80H[5]] = 0.
2. Tasks are used to scale to different output windows, priority on task B after SWRST.
3. Both tasks at 1⁄2 frame rate; OFIDC = 0; subaddresses 90H at 43H and C0H at 42H.
4. In examples 3 and 4 the association between input FID and tasks can be flipped, dependent on which time the SWRST is de-asserted.
5. Task B at 2⁄3 frame rate constructed from neighbouring motion phases; task A at 1⁄3 frame rate of equidistant motion phases; OFIDC = 1;
subaddresses 90H at 41H and C0H at 45H.
6. Task A and B at 1⁄3 frame rate of equidistant motion phases; OFIDC = 1; subaddresses 90H at 41H and C0H at 49H.
7. State of prior field.
8. It is assumed that input/output FID = 0 (= upper lines); UP = upper lines; LO = lower lines.
9. O = data output; NO = no output.
