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;

It is valid only when on-chip resistors are not used (INTRS = "L")
When using internal resistors (INTRS = "H"), open this pin
REF
I
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
VEXT
