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
When the internal power circuit is active, these voltages are generated as following table
I/O according to the state of LCD bias.

V0 voltage adjustment pin
It is valid only when on-chip resistors are not used (INTRS = “L”)
I External VREF input pin for the LCD power supply voltage regulator
Selects the external VREF voltage via the VEXT pin
I
− REF = "H": using the internal VREF
− REF = "L": using the external VREF
