d. LCD drive power supply setting

With this LSI, there are two ways of providing LCD power: by using the on-chip power supply

circuit, or by using an external circuit.

When the on-chip power supply circuit is used for the LCD drive power supply, the V

0 and V1

pins should be interconnected externally, as shown in figure 13.4 (a).

When an external power supply circuit is used for the LCD drive power supply, connect the

external power supply to the V

1 pin, and short the V0 pin to VCC externally, as shown in figure

13.4 (b).

e. Low-power-consumption LCD drive system

Use of a low-power-consumption LCD drive system enables the power consumption required

for LCD drive to be optimized. For details, see section 13.3.4, Low-Power-Consumption LCD

Drive System.
