2 OSC2 terminal. O With this OSC. freq., decides horizontal indicatin and character width.
3 CS Chip select input I
Chip select terminal and turns to “L” when transfer serial data.
Hysteresis input. Pull up resistor is built-in.
4 SCK Serial clock input I
Takes in serial data of SIN at SCK rise when CS terminal is in “L”.
Hysteresis input. Pull up rersist is built-in.
5 SIN Serial data input I
Serial input of register for indication control and data, and address for indication data
memory. Hysteresis input. Pull up rersistor is built-in.
6 AC Auto-clear input I
Resets internal circuit of IC at “L” mode.
Hysteresi input. Pull up resistor is built-in.
