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 f
O
is given by: f
O
= (f
OSC
/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/S15 and KS2/S16
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
An oscillator circuit is formed by connecting an external resistor and
capacitor at this pin.
Serial data interface connections to the controller. Note that DO, being an
open-drain output, requires a pull-up resistor.
CE: Chip enable
CL: Synchronization clock
DI: Transfer data
DO: Output data
This pin must be connected to ground.
