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

OPEN
The S1/P1 to S4/P4 pins 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].

O
OPEN
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
DI: Transfer data

• 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.
