 Description:
                For audio purpose only.
+
                Used by audio driver to set/get the spi input frequency.
+
                This is mandatory if DFSDM is slave on SPI bus, to
                provide information on the SPI clock frequency during runtime
                Notice that the SPI frequency should be a multiple of sample
                frequency to ensure the precision.
-               if DFSDM input is SPI master

+               if DFSDM input is SPI master:
+
                        Reading  SPI clkout frequency,
                        error on writing
+
                If DFSDM input is SPI Slave:
+
                        Reading returns value previously set.
                        Writing value before starting conversions.
