ADC SERIAL PORT SELECT (ADC_SP SELX)
DAC DE-EMPHASIS CONTROL (DAC_DEM)
Selects the required range of sample rates for all converters clocked from the Codec serial port
(CODEC_SP). Bits must be set to the corresponding sample rate range when the CODEC_SP is in Master
or Slave Mode.
Default = 00
00 - Single-Speed Mode (4 to 50 kHz sample rates)

00 - Serial data on CX_SDOUT pin, clocked from the CODEC_SP. S/PDIF data on SAI_SDOUT pin.
01 - Serial data on CX_SDOUT pin, clocked from the SAI_SP. S/PDIF data on SAI_SDOUT pin.
10 - Serial data on SAI_SDOUT pin, clocked from the SAI_SP. No S/PDIF data available.

Function:
Default = 0
Function:
Selects the required range of sample rates for the Serial Audio Interface port (SAI_SP). These bits
must be set to the corresponding sample rate range when the SAI_SP is in Master or Slave Mode.
Selects the desired clocks and routing for the ADC serial output.
Enables the digital filter to maintain the standard 15µs/50µs digital de-emphasis filter response at the
auto-detected sample rate of either 32, 44.1, or 48 kHz. De-emphasis will not be enabled, regardless
of this register setting, at any other sample rate. If the FRC_PLL_LK bit is set to a ‘1’b, the auto-detect
sample rate feature is disabled. To apply the correct de-emphasis filter, use the DE-EMPH bits in the
