Power supply. Connect to MPU power pin V
Externally-input reference power supply for booster circuit.
This is a 0V terminal connected to the system GND.
Multi-level power supply for LCD drive. The voltages are
determined by LCD cell.The voltages should maintain the following
relationship : V
When on-chip power supply circuit turns on, V
generated, and the following voltages are generated to V
Either voltage can be selected by LCD bias set command.
Booster output.
Voltage adjustment pin. Provides V
When internal resistors are used, this pin cannot be used.
8-bit bi-directional data bus to be connected to the standard 8-bit or
16-bit MPU data bus.
When the serial interface is selected (P/S=LOW) ;
Control/data flag input.
Chip select input. Data input is enable when CS is low.
When RES is caused to go low, initialization is executed.
A reset operation is performed at the RES signal level.
Boosting capacitor positive connection pin.
Boosting capacitor negative connection pin.
Boosting capacitor positive connection pin.
Boosting capacitor negative connection pin.
Boosting capacitor positive connection pin.
Boosting capacitor positive connection pin.
A0=HIGH : The data on D7 to D0 is display data.
A0=LOW : The data on D7 to D0 is control data.
D7 : Serial data input (SI)
D6 : Serial clock input (SCL)
