The S1/P1/G1 to S6/P6/G6 pins can be used as general –purpose outputs. - O OPEN COM1 to COM4 51 to 54 Common driver output pins. The frame frequency is fo[Hz]. - O OPEN S52/OSC 60 Segment output. The pin S52/OSC can be used external frequency input pin when set up by the control data. - I/O OPEN SCE SCL SDI 62 63 64 Serial data transfer inputs. Must be connected to the controller. SCE: Chip enable SCL: Synchronization clock SDI: Transfer data H ↑ - I I I GND INHb 61 Display off control input • INHb = low (VSS) ...Display forced off S1/P1/G1 to S6/P6/G6 = low (VSS) S7 to S54 = low (VSS) COM1 to COM4 = low (VSS) Shuts off current to the LCD drive bias voltage generation divider resistors. Stop the internal oscillation circuit. • INHb = high (VDD)...Display on However, serial data transfer is possible when the display is forced off. L I VDD VDD 56 Power supply pin for the logic circuit block. A power voltage of 2.7V to 6.0V must be applied to this pin. - - - VSS 59 Power supply pin. Must be connected to ground. - - - IO Equivalence Circuit Figure 6.
