X X X value used for coring the vertical vector component before application
in the upconverter; range:
0 to 3.5

at logic 0 in normal operation

fallback (

)
single memory film mode control (
double memory or single memory

); should be set in single memory film mode to ensure that only
original lines are selected as output when UpcShFac is 0 or 32

full FALCONIC or single memory type
de-interlacing
)
Bits 3 and 4 are used to control sensitivity to local vector smoothness
(
0
= sensitive to unsmoothness,
3
= hardly sensitive to
unsmoothness). Bits 5 to 7 define the maximum contribution of
non-motion compensated pixels to the output

upconverter goes into protection mode (
