4. Function specifications

4.1 The Serial Interface

When the serial interface has been selected then when the chip is in active state the serial data

input(SI) and the serial clock(SCL) can be received. The serial data is read from the serial data

input pin in the rising edge of the serial clock . When “A0”=“H”, the data is display data, and when

“A0”=“L”, the data is command.

4.2 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.

4.3 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)
