#include <SPI.h>
byte ssPin = 10;
byte testData = 0xAA;  // test data
void setup(){
pinMode (ssPin,  OUTPUT);
digitalWrite (ssPin, HIGH);
}
void loop(){
digitalWrite (ssPin, LOW); // RCLK
SPI.transfer(testData); // SCK to SRCLK, MOSI to SER In. OE Low, MRCLR HIGH
digitalWrite (ssPin, HIGH);
}

Connect Arduino SCK (13) to SRCLK
Connect Arduino MOSI (11) SerData in
Connect Arduino SS (10) to RCLK.
Connect OE/ to GND
Connect SRCLR to +5
Just like the notes I have in the code.
