• TEST1, TEST2, TEST3

Test signal input pins.

The manufacturer uses these pins for testing.

The user should make these pins short-circuited to GND or open.

• OSC1, OSC2, OSC3

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

pin. OSC2 and OSC3 are open during input of external master clock. See diagram below.

• C1 to C17, S1 to 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. During use at 1/9duty, C1 to C9 pins are used, and C10 to C17 pins are set

open. See figure below.

• VDD, VSS

Supply voltage pins. VDD should be set at "H" level.

VSS is a GND pin. If the battery is used, VDD is connected to the + pin, and VSS to the

– pin.
