PIN DESCRIPTION
Pin Name I/O
Description
DIO
I/O
Data Input Output Pin
( N-Channel , Open-Drain) This pin
outputs serial data at the falling edge of
the shift clock. This pin inputs serial data
at the rising edge of the shift clock
(starting from the lower bit)
SCLK
I
Clock Input Pin
This pin reads serial data at the rising
edge and outputs data at the falling edge.
STB
I
Serial Interface Strobe Pin
The data input after the STB has fallen is
processed as a command. When t his pin
is "HIGH", CLK is ignored.
K1，K2

Key Data Input Pins
The data sent to these pins are latched at
the end of the display cycle.(Internal
Pull-Low Resistor)
