Reset input pin for active “L”.
Input and output pins for the main clock generating circuit. Connect a ceramic resonator or
quartz-crystal oscillator between the X
IN
and X
OUT
pins to set the oscillating frequency. If an ex-
ternal clock is used, connect the clock source to the X
IN
pin and leave the X

pin open.
This pin is used as voltage supply input for LCD driver. Input V

When the LCD is operated at 1/5 bias, leave these pins open. When the LCD is operated at 1/4
bias, connect these pins externally.
