Notes about dynamic output section
Note 45: HVDC-VAMP at minimum.
Note 46: HVDC-HPH at medium.
Note 47: Ratio of the amplitude at HDyCorTr=1 to the amplitude at HDyCorTr=0 (refer to chapter "I²C-bus control
register map") as a quadratic function of horizontal size adjustment.
Note 48: (1.38)SHVDC-HSHAP
Note 49: Ratio "A/B"of vertical parabola component voltage at tVR=0 versus vertical parabola component voltage at
tVR=TVR.
Note 50: Refer to Figure 16.
Note 51: Taken for reference at given position of HDyCorPh flag.
Note 52: Unsigned value. Polarity selection by VDyCorPol I²C-bus bit. Refer to section I²C-bus control register map.
Note 53: Value gives the shape characteristics of the H-component. Refer to Figure 17.
Note 54: The flat part begins at the start of fly-back and ends at the same moment as for combination HDCFlatEn = 0,
HDyCorPh = 1. Refer to Figure 16.
