Notes about EW drive section

Note 24: KEYST at medium (neutral) value.

Note 25: TCC at medium (neutral) value.

Note 26: BCC at medium (neutral) value.

Note 27: PCC at minimum value.

Note 28: VPOS at medium (neutral) value.

Note 29: HSIZE I²C field at maximum value.

Note 30: VEW-DC is defined as voltage at tVR=1/2 TVR.

Note 31: Defined as difference of (voltage at tVR=0) minus (voltage at tVR=1/2 TVR).

Note 32: Defined as difference of (voltage at tVR=TVR) minus (voltage at tVR=1/2 TVR).

Note 33: VSIZE at maximum value.

Note 34: Difference (voltage at tVR=0) minus (voltage at tVR=TVR).

Note 35: Ratio "A/B"of parabola component voltage at tVR=0 versus parabola component voltage at tVR=TVR.

See Figure 2.

Note 36: VHEHT>VRefO, VVEHT>VRefO

Note 37: VEW-AC is defined as overall peak-to-peak value between tVR=0 and tVR=TVR of all components other than VEW-

DC (contribution of PCC, keystone correction, corner corrections and S- and W-corrections).

Note 38: More precisely tracking with voltage on HPLL1F pin which itself depends on frequency at a rate given by

external components on PLL1 pins

Note 39: VEW-DC[span] = VEW-DC[VHO>VHOThrfr] - VEW-DC[HSIZE=0000000b].

VEW-AC[fmax] = VEW-AC[VHO>VHOThrfr].

Note 40: Defined as difference of (voltage at tVR=1/4 TVR) minus (voltage at tVR=3/4 TVR).

Note 41: Defined as difference of (voltage at tVR=1/2 TVR) minus (voltage at tVR=1/4 TVR).

Note 42: EWSC at medium (neutral) value.

Note 43: EWWC at medium (neutral) value.

Note 44: Informative, not tested on each unit.
