Power supply pin for logic circuit, +2.2V to 3.3V
Ground pin for logic circuit, connected to 0V
Ground pin for high voltage circuit, connected to 0V
Bias power supply pin for LCD drive voltage
When using an external power supply, convert the impedance by
using resistance-division of the LCD drive power supply or operation
amplifier before adding voltage to the pins. These voltages should
have the following relationship: VSS<V4<V3<V2<V1<V0
When the internal power supply circuit is active, these voltages are
generated by the built-in booster and voltage converter. Then, you
must connect each capacitor to VSS.
Connecting pin for the built in booster’s capacitor + side.
The capacitor is connected between CAP1- and CAP1+.
Connecting pin for the built in booster’s capacitor - side.
The capacitor is connected between CAP1- and CAP1+.
Connecting pin for the built in booster’s capacitor + side.
The capacitor is connected between CAP2- and CAP2+.
Connecting pin for the built in booster’s capacitor - side.
The capacitor is connected between CAP2- and CAP2+.
Connecting pin for the built in booster’s capacitor + side.

Voltage supply pin for the booster circuit. Usually the same voltage
Output pin of boosted voltage in the built-in booster.
The capacitor must be connected between this pin and the VSS.
Output pin for regulator voltage of VBA AMP.
Output pin for temperature compensation output voltage.
level as VDD. In the case of TCP, draw it at a separate terminal.
