The H8S/2268 Group incorporates a triple step-up voltage circuit. Triple voltage of liquid crystal
input reference voltage (V
Before enabling the step-up voltage circuit, duty cycle (1/3 duty or 1/4 duty), LCD driver or I/O
pin function, and display data and frame frequency should be selected. Around 0.1-µF capacitor
should be connected between C1 and C2, and voltage specified in section 25.2.6, LCD
Characteristics should be applied to V3 pin.
After above settings, by selecting the step-up voltage circuit clock in LCD control register 2
(LCR2) and setting SUPS to 1, the triple step-up voltage circuit operates, voltage double of V
is generated for V2 pin, and voltage triple of V
Notes: 1. The triple step-up voltage circuit should only be used as LCD drive power of the
