S5 to S54

1 to 4

5 to 54

Segment outputs for displaying the display data transferred by serial data input.

The S1/P1 to S4/P4 pins can be used as general-purpose output ports when so set

up by the control data.

OSC

55

Oscillator connection. An oscillator circuit is formed by connecting an external

resistor and capacitor to this pin. This pin can be used as the external clock input

pin if external clock operating mode is selected with the control data.

Serial data transfer inputs. Must be connected to the controller.

CE: Chip enable

CL: Synchronization clock

INH

57

Display off control input

• INH = low (VSS) ...Display forced off

S1/P1 to S4/P4 = low (VSS)

(These pins are forcibly set to the segment output port function

and held at the VSS level.)

S5 to S54 = low (VSS)

COM1, COM2 = low (VSS)

OSC = Z (high impedance)

RC oscillation stopped

Inhibits external clock input.

• INH = high (VDD)...Display on

RC oscillation enabled (RC oscillator operating mode)

Enables external clock input (external clock operating mode).

However, serial data transfer is possible when the display is forced off.
