(1) Input vertical trigger pulse to pin VIN.
Pulse level (VT)
= 3.0 V
(2) Set V-DF PHASE (sub-address: 06) to minimum (data: 08) and measure pin 22
(V-DF OUT) phase TVD (08).
(3) Set V-DF PHASE (sub-address: 06) to maximum (data: F8) and measure pin 22
(V-DF OUT) phase TVD (F8).
(4) Calculate change amount TVD using the following formula.
TVD = TVD (08) + TVD (F8)

(1) Connect external supply voltage V7 to TP7 (V NF).
(2) Switch to VD (sub-address: 00) to AC-Coupling mode (data: 81).
(3) Increase external supply voltage V7 from 5.5 V. When D3 data in Read mode
changes from 0 to 1, measure TP7 voltage VVGH.
(4) Decrease external supply voltage V7 from 5.5 V. When D3 data in Read mode
changes from 0 to 1, measure TP7 voltage VVGL.

(CENTER DAC) voltage VCA (00).
(3) Set V CENTERING (sub-address: 05) to maximum (data: FE) and measure pin 2

(2) Set V SHIFT (sub-address: 01) to minimum (data: 80) and measure pin 2 (CENTER
DAC) voltage VCD (80).
(3) Set V SHIFT (sub-address: 01) to maximum (data: 83) and measure pin 2
(CENTER DAC) voltage VCD (83).
