A summary of the frequency ratio restrictions between the bit-rate clock (sclk_out / sclk_in) and the SPI peripheral clock (spi_clk) are described as,
When SPI Controller works as master, the Fspi_clk>= 2 ¡Á (maximum Fsclk_out)
When SPI Controller works as slave, the Fspi_clk>= 6 ¡Á (maximum Fsclk_in)
