Note 20: TCC at medium (neutral) value.
Note 21: BCC at medium (neutral) value.
Note 22: PCC at minimum value.
Note 23: VPOS at medium (neutral) value.
Note 24: HSIZE at minimum value.
Note 25: Defined as difference of (voltage at t_VR=0) minus (voltage at t_VR=1/2 T_VR).
Note 26: Defined as difference of (voltage at t_VR=T_VR) minus (voltage at t_VR=1/2 T_VR).
Note 27: VSIZE at maximum value.
Note 28: Difference (voltage at t_VR=0) minus (voltage at t_VR=T_VR).
Note 29: Ratio "A/B"of parabola component voltage at t_VR=0 versus parabola component voltage at t_VR=T_VR.
Note 30: ς_HEHT>_VRefO, ς_VEHT>_VRefO
Note 31: V_EW-AC is sum of all components other than V_EW-DC (contribution of PCC, keystone correction and corner
corrections).
Note 32: More precisely tracking with voltage on HPLL1F pin which itself depends on frequency at a rate given by
external components on PLL1 pins. V_EW[fmax] is the value at condition V_HO>V_HOThrfr.
