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
according to the state of LCD bias.

I/O Connect this pin to VSS through capacitor.
V0 voltage adjustment pin
I
It is valid only when internal voltage regulator resistors are not used (INTRS = "L").
This is the reference voltage for the voltage converter circuit for the LCD driving.
I Whether internal voltage converter use or not use, this pin should be fixed.
The voltage should have the following range: 2.4V ≤ VCI ≤ 3.6V
This is the external-input reference voltage (VREF) for the internal voltage regulator.
I It is valid only when external VREF is used (REF = "L").
When using internal VREF, this pin is Open
Select the external VREF voltage via VEXT pin
I − REF = "L": using the external VREF
− REF = "H": using the internal VREF
