Function
Active I/O
Segment output for displaying the display data transferred by
-
O
serial data input. The S5/P1/G1 to S10/P6/G6 pins can also
be used as General –purpose / PWM outputs when so set up
by the control data.
Segment output for displaying the display data transferred by
-
O
serial data input. The S11/P7/G7 to S20/P16/G16 pins can
also be used as General –purpose outputs / PWM outputs (by
EXTPWM) when so set up by the control data.
Segment output for displaying the display data transferred by
-
O
serial data input.
Key scan outputs
-
O
Although normal key scan timing lines require diodes to be
inserted in the timing lines to prevent shorts, since these
outputs are unbalanced CMOS transistor outputs, these
outputs will not be damaged by shorting
when these outputs are used to form a key matrix. The
KS1/S23 to KS5/S27 pins can be used as segment outputs
when so specified by the control data.
Key scan inputs
-
I/O
These pins have built-in pull-down resistors.
The KI1/S32 to KI4/S35 pins can be used as segment outputs
when so specified by the control data.
Common driver output pins. The frame frequency is fo[Hz].

Segment output for displaying the display data transferred by
-
I/O
serial data input. The pin PWMIN/S36 can be used external
PWM input pin or segment output when set up by the control
data.
Segment output for displaying the display data transferred by
-
I/O
serial data input. The pin OSCIN/S37 can be used as external
frequency input pin or segment output when set up by the
control data.
Serial data transfer inputs. Must be connected to the
controller.

S5/P1/G1 to S10/P6/G6 = low (VSS)
S11/P7/G7 to S20/P16/G16 = low (VSS)
S21 to S22 = low (VSS)
KS1/S23 to KS5/S27 = low (VSS)
KI1/S32 to KI4/S35 = low (VSS)
PWMIN/S36 = low (VSS)
OSCIN/S37 = low (VSS)
COM1 to COM4 = low (VSS)
Stop the LCD drive bias voltage generation divider resistors.
Stop the internal oscillation circuit.
When INHb = high (VDD), Display on
However, serial data transfer is possible when the display is
forced off.
