ADC FUNCTIONAL MODE (ADC_FMX)
ADC CLOCK SOURCE SELECT (ADC_CLK SEL)
DAC DE-EMPHASIS CONTROL (DAC_DEM)
Default = 00
00 - Single-Speed Mode (4 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 192 kHz sample rates)
11 - Reserved

0 - ADC_SDOUT clocked from the DAC_SP.
1 - ADC_SDOUT clocked from the ADC_SP.
Function:
Default = 0
Function:
Selects the required range of sample rates for the ADC serial port (ADC_SP). These bits must be set
to the corresponding sample rate range when the ADC_SP is in Master or Slave Mode.
Selects the desired clocks 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
Interrupt Control (address 1Eh) register to set the appropriate sample rate.
