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