4. Function specifications

4.1 Basic Setting

To drive the LCD module correctly and provide normally display, please use the following setting

- ADC = 0 (normal)

- SHL select = 1 (reverse)

- LCD Bias Select = 1/9

- Initial Display Line = 0

- Entire Display ON/OFF = OFF (normal)

- Reverse Display ON/OFF = OFF (normal)

- Set Power Control Set:

voltage follower = ON, voltage converter = ON, voltage regulator = ON

- Display ON/OFF = ON

Note:

*1. These setting/commands should issue the LCD module while start up.

*2. See the Display Commands section for details.

4.2 Resetting the LCD module

The LCD module should be initialized by using /RES terminal.

While turning on the VDD and VSS power supply, maintain /RES terminal at LOW level. After the

power supply stabilized, release the reset terminal (/RES=HIGH)

4.3 Application Circuit (example)

Two external capacitors are needed for booster as follows(C1,C2 =1.0uF),

R1 is not installed by default (R1 reserved for abnormal power off procedure)
