3. Change unicolor data to maximum (7F), center (40), and minimum (00), and
measure pin 12 picture period amplitude V_uCYMAX, V_uCYCNT, and V_uCYMIN
respectively.
4. Determine unicolor amplitude ratio between maximum and minimum in
decibels. (∆V_uCY)
5. Repeat the steps 2 to 4 above with the following pins: Input (picture period
amplitude 0.2 Vp-p) from pin 67, and measure pin 14.
