1. The generator treats double-clocking and pixel repetition as two totally separate items. NCPP controls the number of clocks
per pixel, while NPPP controls pixel repetition factor. All library formats set pixel repetition factor NPPP to zero (i.e. OFF) by
default. Double-clocking and pixel repetition cannot be applied simultaneously due to AVI:RP field constraints. Therefore, dou-
ble-clocked formats do not support pixel repetition. Pixel repetition is only applicable to the "4x" formats, where HRES remains
at 2880-pixels as the pixel repetition factor NPPP is varied between 1 and 10 - thereby varying the effective resolution.
2. EXCX and EXAR are not listed here, because all library formats set EXCX and EXAR equal to N0 and CXAR, respectively.
These values may be subsequently changed by rendering a special test image called "AFDtest", after the base format has
finished loading, in order to evaluate different AFD cases.
3. TUNE is a flag that indicates whether the frequencies of a format have been detuned or not. A value of one indicates that all
of the frequencies of a format have been tuned by a factor of 1/1.001 for NTSC compatibility. A value of zero, on the other
hand, indicates that the format has not been so tuned.
4. Double-clocked formats have the same horizontal resolution as single-clocked formats - the horizontal active (as we define it),
is not doubled in the double-clocked case. Some formats are distinguished by a horizontal active that is 4-times the normal
value of 720. Here, pixel repetition may be applied, by a special "PixelRep" test image, after the format has loaded. The "Pix-
elRep" test image allows the number of pixels-per-pixel (NPPP) to be varied and an image with repeated pixels to be rendered
for test purposes.
5. Some formats are distinguished by having a slightly different vertical line total.
