Note 1) The numerals in the bracket [ ] show the step-up scale from Vci1.
Note 2) The capacitor connection pins are step-up capacitors which are necessary for DDVDH, VCL, VGH,
VGL voltages.
Note 3) Set the voltage within the following range: DDVDH = 5.5 V (Max.), VCL = - 3.3 V (Min.),
VGH = 16.5 V (Max.), VGL = -16.5 V (Min.)
