I/O
Description
OSC
Oscillator Input Pin
I A resistor is connected to this pin to
determine the oscillation frequency
DOUT
Data Output Pin (N-Channel, Open-Drain)
O This pin outputs serial data at the
falling edge of the shift clock.
Data Input Pin
DIN
I This pin inputs serial data at the rising edge
of the shift clock (starting from the lower bit)
CLK
I
Clock Input Pin This pin reads serial data at the rising edge
and outputs data at the falling edge.
Serial Interface Strobe Pin
STB
I
The data input after the STB has fallen
is processed as a command. When this
pin is HIGH", CLK is ignored.
K1, K2
Key Data Input Pins
I The data sent to these pins are latched at the end
of the display cycle. (Internal Pull-Low Resistor)
