Notes 1.
2.
This is the wait time from when voltage boosting is started (VAON0 = 1) until display is enabled
(LCDON0 = 0).
The voltage differential is the difference between the segment and common signal output’s actual and
ideal output voltages.
Remark
c1: Capacitor connected between CAPH and CAPL
c2: Capacitor connected between VLC0 and ground
c3: Capacitor connected between VLC1 and ground
c4: Capacitor connected between VLC2 and ground
