Segment outputs for displaying the display data transferred by serial data input.
The S1/P1 to S4/P4 pins can be used as general-purpose output ports under serial
data control.
Common driver outputs
The frame frequency fo is given by : fo = (fOSC/384)Hz.
Key scan outputs
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/S24 and KS2/S25 pins can be used as segment outputs when so
specified by the control data.
Key scan inputs
These pins have built-in pull-down resistors.
Oscillator connection
