If Integration Time < Core Frame Time, Real Frame Time is
2(208 + 640)SCPs + 480(208 + 640)SCPs + 8(208 + 640)SCPs
= 415520 SCPs =415520 X 80ns = 33.24msec = 30fps
else Real Frame Time is
Integration Time * SCPs + 8 * (208 +640) SCPs.
HOLD SLOT in frame timing appears only if integration time is larger then core frame time
