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

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

It is valid only when on-chip resistors are not used (INTRS = "L")
When using internal resistors (INTRS = "H"), open this pin
Selects the external VREF voltage via the VEXT pin
REF = “H”: using the internal VREF
REF = “L”: using the external VREF
Externally input reference voltage (VREF) for the internal voltage regulator
It is valid only when REF is "L"
When using internal voltage regulator, connect to VDD, VSS or open this pin
When using internal clock oscillator, connect a resistor between OSC1 and VDD.
