LCD driver supply voltages. The voltage determined by LCD pixel is
impedance-converted by an operational amplifier (OPA) for
application. Voltages have the following relationship:
V0
V1
V2
V3
V4
VSS
When the internal power circuit is active, these voltages are
generated according to the state of LCD bias, The selection of
voltages is determined by the “LCD bias select” instruction, as
shown in the table below.
