DETAIL_ENH[9:0]
UC
Defines the detail enhancement configuration. The upper five
bits of this word adjust the high frequency detail in the image.
The lower 5-bits control the resolution or granularity. A higher
value represents more detail with higher granularity.
Detail Enhancement = Y / X
Y = DETAIL_ENH[9:5]

MSF[18:0]
UC
Represents the number of pixels per smallest active field
divided by a scaling factor required to estimate same frame
detection. A higher value also means vertical edges will have
more effect on the detection of same frames. The equation is
as follows:
MSF = #active_pixels_per_smallest_field / 2

DIFF3T[18:0]

Represents the number of active pixels per smallest field
divided by a factor required to estimate the odd and even
