PIN LIST AND DESCRIPTIONS
GR4 to GR1
A resistor is connected to this pin to determine the
I SG1-SG13 output current and internal oscillation
Data Input - Output Pin
This pin inputs serial data at the rising edge of the
clock (starting from the bit).
Data Output Pin - N-Channel, Open-Drain
This pin outputs serial data at the falling edge of the
Clock Input Pin
I This pin reads serial data at the rising edge and output
data at the falling edge.
Serial Interface Strobe Pin
I The data input after the STB has fallen is processed.
When this pin is HIGH, CLK is ignored.
Key Data Input Pins
I The data sent to these pins are latched at the end of
the display cycle. (Internal Pull-Low Resistor).
