If 1/9 duty is selected, common outputs C10 to C17 should be set open.
Test signal input pins.
The manufacturer uses these pins for testing.
The user should connect this pin to GND or leave open.
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.
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".
