CCS/SECDEVTOOL-OMAPL138C6748: How to set register values of AFE5809 EVM using SPI module of OMAP L138 LCDK

Part Number:SECDEVTOOL-OMAPL138C6748

Tool/software: Code Composer Studio

Dear Friends,

I would like to initialize our AFE5809EVM using our OMAP L138 LCDK. In order to initialize AFE5809EVM , the following two registries of AFE5809EVM should be set via SPI.

Register 0x16 = 0x01

Register 0x04 = 0x18

The OMAP L138LCDK Starterware has an example project, namely, "spi+c674x_omapl138_lcdk". This example clearly demonstrates how we can send and receive commands via the SPI module of the OMAP L138LCDK. I also know how to connect the SPI of OMAP L138 LCDK to the SPI of AFE5809EVM. 

Question: I don't know how to write in CCS that send these register values. Here is a snapshot of the C code used to transmit and receive:

/*
** Enables SPI Transmit and Receive interrupt.
** Deasserts Chip Select line.
*/
static void  SpiTransfer(void)
{
    p_tx = &tx_data[0];
    p_rx = &rx_data[0];
    SPIIntEnable(SOC_SPI_1_REGS, (SPI_RECV_INT | SPI_TRANSMIT_INT));
    while(flag);
    flag = 1;
    /* Deasserts the CS pin(line) */
    SPIDat1Config(SOC_SPI_1_REGS, SPI_DATA_FORMAT0, 0x4);
}

How can I write in my SPI code: find register number "0x16" and set its value to "0x01"? 

Thank you
