The S1/P1 to S8/P8 pins can be used as general-purpose output ports under serial data control. Common driver outputs. The frame frequency fo is fOSC/512 Hz. Oscillator connection. An oscillator circuit can be formed by connecting an external resistor and capacitor at this pin. Serial data transfer inputs. Connected to the controller. CE: Chip enable CL: Synchronization clock DI: Transfer data Display off control input INH = low (VSS) ......Display forced off S1/P1 to S8/P8 = low (VSS) (These pins are forcibly set to the segment output port function and held at the VSS level.) S9 to S66 = low (VSS) COM1 to COM4 = low (VSS) INH = high (VDD).....Display on However, serial data transfer is possible when the display is forced off by this pin. Used to apply the LCD drive 2/3 bias voltage externally. Connect this pin to VLCD2 when using a 1/2-bias drive scheme. Used to apply the LCD drive 1/3 bias voltage externally.
