nRF9E5, pi, spi, TE, AD

这是nRF9E5的初始化的一些程序。如下：

unsigned char SpiReadWrite(unsigned char b)
{
    EXIF &= ~0x20;                  // Clear SPI interrupt
    SPI_DATA = b;                   // Move byte to send to SPI data register
    while((EXIF & 0x20) == 0x00)    // Wait until SPI hs finished transmitting
        ;
    return SPI_DATA;
}

void Init(void)
{
    unsigned char tmp;

//SPI 设置

    SPICLK = 0;                     // Max SPI clock
    SPI_CTRL = 0x02;                // Connect intewrnal SPI controller to Radio

    // Configure Radio:
    RACSN = 0;
    SpiReadWrite(WRC | 0x03);       // Write to RF config Rx_deepess 3 (RX payload)}、
    SpiReadWrite(0x01);             // One byte RX payload
    SpiReadWrite(0x01);             // One byte TX payload
    RACSN = 1;}

请问一下SpiReadWrite(WRC | 0x03);  什么意思啊？

WRC不是写RF配置寄存器嘛？与0x03或一下代表什么呢？请赐教！谢谢！
