Segment outputs for displaying the display data transferred by serial data
input. The S1/P1 to S8/P8 pins can be used as general-purpose output ports
under serial data control.
Common driver outputs.
The frame frequency is fO[Hz].
The COM4/S74 pin can be used as a segment output in 1/3 duty.

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/S75
