Arduino SPI Usage

[ozkenali]

I am trying to make a project. I have pwm chipset.

In datasheet it says first two bit for read or write. Next 6 bit for adress and then next 24 bits frequence information.

I made a program in arduino uno. But it is not work. I want to ask someone is it possible to send 24 bit as my program? Is should sending I don't know and there is no way to control to am I send program or not. Any suggestion?

#include <SPI.h>

void setup() {
  pinMode(10, OUTPUT); 
  SPI.begin();         
  SPI.setBitOrder(MSBFIRST);
}

void loop() {
    digitalWrite(10, LOW);            
    delay(100); 
    SPI.transfer(B10000011); 
    SPI.transfer(B00000000); 
    SPI.transfer(B00000000); 
    SPI.transfer(B00000010); 
    digitalWrite(10, HIGH);           
    delay(1000);
}

SPI.transfer(B10000011);

That's 00 000011 which is Write Register 3. The FREQ register is register 0. I don't know what goes into Register 3.
