TMS320F28379D中怎么将SPIA配置为MASTER进行主从机通讯

请问你还是需要进行同一芯片的SPIA和SPIB通讯，并且SPIA作为主机吗？例程中就是将SPIA配置为master进行演示的。

void InitSpi(void)

{

   // Initialize SPI-A

   // Set reset low before configuration changes

   // Clock polarity (0 == rising, 1 == falling)

   // 16-bit character

   // Enable loop-back

   SpiaRegs.***.bit.SPISWRESET = 0;

   SpiaRegs.***.bit.CLKPOLARITY = 0;

   SpiaRegs.***.bit.*** = (16-1);

   SpiaRegs.***.bit.SPILBK = 1;

   // Enable master (0 == slave, 1 == master)

   // Enable transmission (Talk)

   // Clock phase (0 == normal, 1 == delayed)

   // SPI interrupts are disabled

   SpiaRegs.***.bit.MASTER_SLAVE = 1;

   SpiaRegs.***.bit.TALK = 1;

   SpiaRegs.***.bit.CLK_PHASE = 0;

   SpiaRegs.***.bit.SPIINTENA = 0;

   // Set the baud rate

   SpiaRegs.SPIBRR.bit.SPI_BIT_RATE = SPI_BRR;

   // Set FREE bit

   // Halting on a breakpoint will not halt the SPI

   SpiaRegs.SPIPRI.bit.FREE = 1;

   // Release the SPI from reset

   SpiaRegs.***.bit.SPISWRESET = 1;

}

请问当我设置spia和spib的时候InitSpiaGpio()这个函数 我是这么写的，但是不确定是否正确。代码如下。
