Apply power source voltage to VCC, and 0 V to VSS.
Reset input pin for active “ L.”
Input and output pins for the main clock generating circuit.
Connect a ceramic resonator or a quartz-crystal oscillator between the XIN and XOUT pins to
set the oscillation frequency. When an external clock is used, connect the clock source to XIN,
and leave XOUT pin open.
Feedback resistor is built in between XIN pin and XOUT pin.
Input 0
≤ VL1 ≤ VL2 ≤ VL3 ≤ VCC voltage.
Input 0 – VL3 voltage to LCD.
LCD common output pins.
COM2 and COM3 are not used at 1/2 duty ratio.
COM3 is not used at 1/3 duty ratio.
LCD common/segment output pins.
8-bit I/O port.
