Function
Active I/O
Segment output for displaying the display data transferred by
-
O
serial data input. The S1/P1/G1 to S6/P6/G6 pins can also be
used as General –purpose outputs 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/S53 to KS6/S58 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/S59 to KI5/S63 pins can be used as segment
outputs when so specified by the control data.
Common driver output pins. The frame frequency is fo[Hz].
-
O
COMMON / SEGMENT output for LCD driving
-
O
Assigned as COMMON output in 1/8, 1/7, 1/5, Duty modes
and SEGMENT output in 1/1 Duty, 1/3 Duty and 1/4 Duty
modes
Segment output for displaying the display data transferred by
-
I/O
serial data input.
The pin OSC_IN/S70 can be used as external frequency
input pin when set up by the control data.
Serial data transfer inputs. Must be connected to the
controller.
