Test signal input pins.
The manufacturer uses these pins for testing.
The user should make these pins short-circuited to GND or open.
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.
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.
