: Segment output pins
: Segment output or DSP input pins
: Segment output or AD input pins
: Segment output of DSP output pin
: Segment output or AD output pins
: Common output pins (Only COMI is used at time of 1.71 duty. and COM2 is set open)
: LCD bias voltage setting pin
: Oscillation pin
: Input pin for serial data transfer
: Supply pins
: Display-off input pin. (Valid only with the otitput driver. This means that the transfer of serial data is possible while the
display is off.)
: No connection is made.
