(7) Voltage setting at power pins (V3, V2 and V1) for driving LCD
Set the voltages at the LCD power pins (V3, V2 and V1) as shown below.
A connection example for supply power to drive the LCD is shown in
Fig. 2.25.
Fig. 2.25 Connection Examples for Supply Power for Driving LCD
Note: To set a 1/2 bias when using the external dividing resistor (ladder
circuit), short-circuit the pins V2 and V1.
Built-in voltage dividing resistor
The built-in voltage dividing resistors are connected as shown in Fig. 2.26.
Writing 1 at the VSEL bit connects the built-in voltage dividing resistors.
Therefore, write 1 at the VSEL bit to connect the resistors and set 0 to
disconnect the resistors.
The built-in voltage dividing circuit is connected to the VSS through the
transistor within chip. Therefore, the current flowing into the resistor can
be cut when the LCD stops.
