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

Voltages should have the following relationship: VDD ≤ VCI ≤ V0
I
V0 voltage adjustment pin
It is valid only when on-chip resistors are not used (INTRS = "L")
Selects the external VREF voltage via VEXT pin
I − REF = "L": using the external VREF
− REF = "H": using the internal VREF
I
Externally input reference voltage (VREF) for the internal voltage regulator
It is valid only when REF is "L".
