If 1/9 duty is selected, common outputs C10 to C17 should be set open.

• TEST1, TEST2, TEST3

Test signal input pins.

The manufacturer uses these pins for testing.

The user should connect this pin to GND or leave open.

• OSC1, OSC2, OSC3

Pins used for 80kHz RC oscillation circuit formation and as external master clock input

pin. Leave OSC2 and OSC3 open during input of external master clock.

• C1 - C17, S1 - S80 (Common 1 - 17, Segment 1 - 80)

LCD output pins to be connected with the LCD panel. Turning into AC is made by frame

inversion.

Use the C1 to C9 pins during use at 1/9 duty, and leave the C10 to C17 pins open.

ÆRefer to "Relationship between panel and LCD output".
