The pins S1/P1 to S8/P8 can be used as general-purpose output ports when so set up by the control data. Common driver outputs. The frame frequency is fO Hz. The COM4/S87 pin can be used as a segment output in 1/3 duty. Oscillator connection. An oscillator circuit is formed by connecting an external resistor and capacitor to this pin. Serial data transfer inputs. These pins are connected to the control microprocessor. CE: Chip enable CL: Synchronization clock DI: Transfer data Display off control input • INH = low (VSS) ....Off S1/P1 to S8/P8 = low (VSS) (These pins are forcibly set to the segment output port function and fixed at the VSS level.) S9 to S86 = low (VSS) COM1 to COM3 = low (VSS) COM4/S87 = low (VSS) • INH = high (VDD) ..On Note that serial data transfers can be performed when the display is forced off by this pin. Used to apply the LCD drive 2/3 bias voltage externally. This pin must be connected to VLCD2 when 1/2 bias drive is used. Used to apply the LCD drive 1/3 bias voltage externally. This pin must be connected to VLCD1 when 1/2 bias drive is used. Logic block power supply. Provide a voltage in the range 2.7 to 6.0 V. LCD driver block power supply. Provide a voltage in the range 2.7 to 6.0 V. — — — H — L — — — — O O I/O I I I I I I — — Open Open VDD GND GND Open Open — — 97 95 VSS Ground pin.
