SPI status register unresponsive

Can anyone tell me why even setting SPIEN in MR, SPIENS bit is not set in STATUS register. I have enabled local loopback for testing in master mode only. I have used the at91lib library from atmel.
the code is as shown:-
here is the code in which i have enabled local loopback mode. I just want to test if data arrives in RDR or not.

void SPI_Enable(AT91S_SPI *spi)
{
    spi->SPI_CR = AT91C_SPI_SPIEN;
}

void SPI_Configure(AT91S_SPI *spi,
                          unsigned int id,
                          unsigned int configuration)
{
    AT91C_BASE_PMC->PMC_PCER = 1 << id;
    spi->SPI_CR = AT91C_SPI_SPIDIS;
    spi->SPI_CR = AT91C_SPI_SWRST;
    spi->SPI_MR = configuration;
}

void SPI_ConfigureNPCS(AT91S_SPI *spi,
                              unsigned int npcs)
{
    spi->SPI_CSR[npcs] = 0x2201AA0A;
}

void SPI_Write(AT91S_SPI *spi, unsigned short data)
{
        while ((spi->SPI_SR & AT91C_SPI_TXEMPTY) == 0);
        spi->SPI_TDR = data | 0xE << 16;
        while ((spi->SPI_SR & AT91C_SPI_TDRE) == 0);
}

unsigned short SPI_Read(AT91S_SPI *spi)
{
    while ((spi->SPI_SR & AT91C_SPI_RDRF) == 0);
    return spi->SPI_RDR & 0xFFFF;
}
