Notes 1. This is a capacitor that is connected between voltage pins used to drive the LCD.
C1: A capacitor connected between CAPH and CAPL
C2: A capacitor connected between V
C3: A capacitor connected between V
C4: A capacitor connected between V
2. This is the wait time from when voltage boosting is started (VAON0 = 1) until display is enabled
(LCDON0 = 1).
3. The voltage differential is the difference between the segment and common signal output's actual and
ideal output voltages.
