8. POWER SEQUENCE
The µPD161401 has on-chip power circuits such as a booster circuit and a voltage follower circuit. Resetting by the
/DISP pin should only be used to prevent malfunctioning due to noise.
If charge remains in the smoothing capacitor connected between the LCD drive pins (VLCD, VLC1 to VLC4) and VSS, the
display screen may momentarily blackout when power is turned ON or OFF. It is therefore recommended to turn
ON/OFF power in the following sequence to avoid any trouble.
