Description
Pin No.
Oscillator Input Pin
OSC
I A resistor is connected to this pin to determine
1
the oscillation frequency
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.
