Segments outputs for displaying the display data transferred by serial data
input. The S1/P1 to S8/P8 pins can be used as general-purpose output
ports under serial data control.
Common driver outputs. The frame frequency fo is f

/512 Hz.
Oscillator connection. An oscillator circuit can be formed by connecting an
external resistor and capacitor at this pin.
Serial data transfer inputs. Connected to the controller.
