I/O
O Segment outouts for displaying the display data transferred by serial data input.
The S1/P1 to S4/P4 pins can be used as generalpurpose output ports under serial data control.
O Common driver outputs.
The frame frequency f0 is given by :
f0 = (FOSC/384)Hz.
I/O Oscillator connection
An oscillator circuit is formed by connecting an external resistor and capacitor to this pin.
I
Serial data transfer inputs.

I Display off control input
• INH= "L"(VSS) ---Display forced off
S1/P1 to S4/P4 = "L"
(These pins are forcibly set to the segment output port function and held at the low level.)
S5 to S68 = "L"
COM1 to COM3"L"
• INH = "H"(HDD)---Display on
However, serial data transfer is possible when the display is forced off by this pin.
I Used for applying the LCD drive 2/3 bias voltage externally. Must be connected to VDD2 when a 1/2
bias drive scheme is used.

- Power supply connection. Provide a voltage of between 3.0 and 6.0V.
- Power supply connection. Connect to ground.
