This is the external input VREG power supply for the LCD power supply
voltage adjustment circuit.
(This pin should be left open when not used as an external input)
This pin is effective only in the case of optional devices with the VREG
external input option.
These are the output pins during voltage multiplication. Connect a
capacitor between these pins and V
SS
.
These are the multiple level power supply pins for the LCD power supply.
The voltages specified for the LCD cells are applied to these pins after
resistor network voltage division or after impedance transformation using
operational amplifiers. The voltages are specified taking V
SS
as the
reference, and the following relationship should be maintained among
them.

Master operation: When the power supply is ON, the following voltages
are applied to V2 to V5 from the built-in power supply circuit. The
selection of voltages is determined by the LCD bias set command.

Voltage adjustment pins. Voltages between V1 and VSS are applied
using a resistance voltage divider.
These pins are effective only when the internal resistors for voltage V1
adjustment are not used (IRS = "L").
Do not use these pins when the internal resistors for voltage V1
adjustment are used (IRS = "H").
These are the pins for connecting the positive side of the capacitors for
voltage multiplication.
Connect capacitors between VS1– and these pins.
These are the pins for connecting the negative side of the capacitors for
voltage multiplication.
Connect capacitors between these pins and VC1+, VC3+, and VC5+.
