LCD SEG-driver outputs.
The display data and the polar-signal (M) control the output voltage of SEG-driver.
LCD COM-driver outputs.
The internal scanning data and the polar-signal (M) control the output voltage of COM-driver.
Reset input pin. When RSTB is “L”, internal initialization procedure is executed.
These pins select interface operation mode.
Note: Refer to “Interface Selection” for detailed information.
Chip select input pin.
CSB=“L”: This chip is selected and the MPU interface is active.
CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance).
The function of this pin is different in parallel and serial interface.
Read / Write execution control pin. (This pin is only used in parallel interface)
This pin is not used in serial interfaces and should be connected to VDD1.

In parallel interface: A0 is register selection input.
A0 = "H": inputs on data bus are display data;
A0 = "L": inputs on data bus are command.
In serial interface: this pad will be used as SCL (serial-clock) input
