Function

Segment outputs that display the data transferred as serial data

Common driver outputs. The frame frequency is fO=(fOSC/384)Hz.

Oscillator connection

(for generating the common segment alternation waveform)

Serial data transfer pins : connected to the

microprocessor.

CE: chip enable

CL: synchronization clock

DI: transfer data

Forcibly turns off the display without regard for the internal data.

Serial data can always be input, whatever the state of this pin.

Used for the 2/3 bias voltage when bias voltages are provided externally.

Connect to VDD2 when 1/2 bias is used.

Used for the 1/3 bias voltage when bias voltages are provided externally.

Connect to VDD1 when 1/2 bias is used.
