setting BitOrder(LSB or MSB) in SPI for TM4C1294ncpdt

Hi,

          I am working on SPI communication for a DMD display.i am Coding in ccs reffering to example code in Aurdino for TM4C1294NCPDT.

Bellow is the code 

DMD()
{

// initialize the SPI port
SPI.begin(); // 
SPI.setBitOrder(MSBFIRST); //
SPI.setDataMode(SPI_MODE0); // CPOL=0, CPHA=0
SPI.setClockDivider(SPI_CLOCK_DIV4); 

}

I have configured code for SPI as above except setBitOrder. I didn't find any API as Such to send LSB or MSB or nether in registers. And on testing the Code without setting setBitOrder in display am not getting desired o/p. i think i cannot neglect it.
