When chip select is not active, DB6 and DB7 may be
high impedance.
Voltage converter input/output pin.
LCD driver supply voltages.
The voltage determined by LCD pixel is
impedance-converted by an operational amplifier for
application.
Voltages should have the following relationship:
V0>=V1>=V2>=V3>=V4>=VSS
