Oscillator input pin, determine the oscillation frequency by a resistor which
is connected to this pin.
Data input pin. This pin inputs serial data at the rising edge of the shift clock
(starting from the lower bit).
Clock input pin. This pin reads serial data at the rising edge.
Serial interface strobe pin. The data input after the STB has fallen is
processed as a command. When this pin “ HIGH” , CLK is ignored.
Logic Power supply.
Segment output pins (p-channel. Open drain).
Segment output Pin/Grid output pin (CMOS output).
